JavaScript can change HTML content, attributes, styles, and validate data. It can be placed in the <body> and <head> sections between <script> tags. Functions and events allow JavaScript code to run when events occur. JavaScript can output to alerts, the document, elements, and the console. It uses data types like numbers, strings, Booleans, arrays, and objects. Conditionals like if/else and switch statements allow different code blocks to run based on conditions. Loops like for, for/in, while, and do/while repeat code.
JavaScript is a client-side scripting language that can be inserted into HTML pages to make them interactive. It allows dynamic validation of forms, changing HTML element properties like visibility, and reacting to user events like clicks or form submissions. The Document Object Model (DOM) represents an HTML or XML document as a tree structure, allowing JavaScript to programmatically access and modify the content, structure, and styling of the document. Common built-in JavaScript objects include String, Date, Array, Math, and Boolean, which provide properties and methods for manipulating text, dates, lists of values, numbers, and true/false values.
JavaScript variables hold values and are declared with var. Variable names are case sensitive and must begin with a letter or underscore. Variables can hold numbers, strings, Booleans, objects, and null values. Arrays are objects that hold multiple values in a single variable. Functions are blocks of code that perform tasks and are executed by events or calls. Objects store related data and functions to represent self-contained entities.

Genetically engineered seeds that are non-renewable, or "seed suicide", have led to increased farmer suicides in India. Known as terminator seeds, they must be repurchased each season rather than allowing harvest of future generations. When farmers take on debt to purchase the seeds but face crop failures or losses, landlords often seize their land, leaving farmers with no alternative but suicide. In contrast, sustainable agriculture aims to meet current needs without compromising future generations through practices that integrate environmental protection, economic viability, and social equity such as crop rotation and soil amendment.

programming language, and a list of minimum
requirements to begin working with PHP.
• PHP is a recursive acronym for "PHP: Hypertext
Preprocessor".
M.S. Chahar
3. • PHP is a server side scripting language that is
embedded in HTML. It is used to manage dynamic
content, databases, session tracking, even build entire
e-commerce sites.
• It is integrated with a number of popular databases,
including MySQL, PostgreSQL, Oracle, Sybase, Informix,
and Microsoft SQL Server.
• PHP is pleasingly zippy in its execution, especially when
compiled as an Apache module on the Unix side. The
MySQL server, once started, executes even very
complex queries with huge result sets in record-setting
time.
• PHP supports a large number of major protocols such
as POP3, IMAP, and LDAP. PHP4 added support for
Java and distributed object architectures (COM and
CORBA), making n-tier development a possibility for
the first time. M.S. Chahar
4. Characteristics of PHP
• Five important characteristics make PHP's
practical nature possible:
• Simplicity
• Efficiency
• Security
• Flexibility
• Familiarity
M.S. Chahar
5. What is PHP?
• PHP is a scripting language, created in 1994 by
Rasmus Lerdorf, that is designed for producing
dynamic Web content.
• PHP originally stood for “Personal Home
Page,” but as its functionality expanded, it
became “PHP: Hypertext Processor” because
it takes PHP code as input and produces HTML
as output.
M.S. Chahar
6. • PHP is typically used for Web-based
applications, it can also be used for command-
line scripting – a task commonly handled by
Perl – as well as client-side applications
(possibly with a graphical user interface) – a
task commonly handled by Python or Java.
• NOTE: This course only addresses PHP in the
context of dynamic Web content creation.
M.S. Chahar
7. PHP is…
• Interpreted rather than compiled like Java or C.
• An embedded scripting language, meaning that
it can exist within HTML code.
• A server-side technology; everything happens on
the server as opposed to the Web browser’s
computer, the client.
• Cross-platform, meaning it can be used on Linux,
Windows, Macintosh, etc., making PHP very
portable.
M.S. Chahar
8. PHP does not…
• Handle client-side tasks such as creating a new
browser window, adding mouseovers,
determining the screen size of the user’s
machine, etc. Such tasks are handled by
JavaScript or Ajax (Asynchronous JavaScript and
XML).
• Do anything within the Web browser until a
request from the client has been made (e.g.,
submitting a form,
• clicking a link, etc.).
M.S. Chahar
9. Why use PHP?
• PHP has been described as being “better, faster, and
easier to learn than the alternatives.” (Ullman, 2004)
The alternatives being…
• HTML – static, no database/file interaction, cannot
handle email, etc.
• CGI (Common Gateway Interface) scripts – Perl or C.
• Microsoft ASP (Active Server Pages), or ASP.NET –
need to learn VBScript, C#, or another language and is
limited to servers running Microsoft Windows Server.
• JSP (JavaServer Pages) – Java-based, so there is a
higher learning curve plus you deal with the overhead
of a
• compiled language: JavaServer sites are slower than
other sites.
M.S. Chahar
10. • PHP is free, works on multiple platforms, and
is open source (i.e., user-driven development,
not part of a corporation). These attributes
combined with a large development
community and the wealth of available PHP
libraries make PHP an attractive choice for
Web developers.
M.S. Chahar
11. Cont….
• The Web content delivery process has the same
beginning and end: A user requests a URL from
the Web server, and HTML markup is sent to the
user’s browser. With the static HTML delivery
process, the Web server sends the exact content
of the requested page to the client without any
additional processing. With dynamic Web
content creation, PHP acts as a filter by
processing PHP code – possibly embedded within
HTML markup – to produce HTML markup that is
ultimately sent to the user’s browser.
M.S. Chahar
12. PHP requirements
• The following elements represent the minimum
requirements to begin working with PHP. Concepts such as
PHP installation and configuration are beyond the scope of
this course.
• PHP-enabled Web server. The EECS/Claxton Web server is
running PHP 5.2.
• If you are working on your own machine, you will need an
SFTP client to transfer your PHP scripts to the Webserver.
Otherwise, you can edit your files directly on the file
system via an SSH session with a text editor (e.g., vi,
emacs).
• Web browser (e.g., Mozilla Firefox, Apple Safari, Microsoft
Windows Internet Explorer).
M.S. Chahar
13. Benefits of Using PHP for Custom
Web Development
• PHP is the ruling language in the world of web design
and development industry. This server-side scripting
language has been especially designed for web
development and can be embedded into HTML.
• The usage of PHP web development service, the
language has prevailed in the industry since its advent.
Most of the web designing and development
companies put their efforts, time and resources in
mastering this language, and the trained PHP
developers helped the end users to get user friendly,
cost-effective and impressive websites.
M.S. Chahar
14. • The flexibility, usability and scalability provided
by PHP development won the hearts of
developers, site owners, as well as of the users.
• The dynamic PHP websites took less time to load
and were extremely easy to operate. Apart from
these benefits bestowed upon the end users, PHP
holds several benefits for the site owners too.
Out of the several ones, here are the four
exclusive benefits of using this language for
custom website development.
M.S. Chahar
15. • Cost Savings
• Freedom of Choice
• Support for Databases
• Easy Availability of Resources
M.S. Chahar
16. Hello print PHP Example
• <?php //start php tags
• echo "hello m s chahar"; //print statement
• ?> //end php tags
M.S. Chahar
17. Commenting PHP Code:
• A comment is the portion of a program that
exists only for the human reader and stripped
out before displaying the programs result.
There are two commenting formats in PHP:
• Single-line comments: They are generally
used for short explanations or notes relevant
to the local code. Here are the examples of
single line comments.
M.S. Chahar
18. Single-line comments
<?
# This is a comment, and
# This is the second line of the comment
// This is a comment too. Each style comments
onlyprint "An example with single line
comments";
?>
M.S. Chahar
20. <?
# First Exampleprint <<<END
This uses the "here document" syntax to outputmultiple
lines with $variable interpolation. Notethat the here
document terminator must appear on aline with just a
semicolon no extra whitespace!
END;
# Second Exampleprint "This spansmultiple lines. The
newlines will beoutput as well";
?>
M.S. Chahar
21. Multi-lines comments
• Multi-lines comments: They are generally
used to provide pseudocode algorithms and
more detailed explanations when necessary.
The multiline style of commenting is the same
as in C. Here are the example of multi lines
comments.
M.S. Chahar
22. <?
/* This is a comment with multiline Author :
Mohammad Mohtashim Purpose: Multiline
Comments Demo Subject: PHP */
print "An example with multi line comments";
?>
M.S. Chahar
23. PHP Variable Types
• The main way to store information in the
middle of a PHP program is by using a
variable.
– The most important things to know about
variables in PHP.
M.S. Chahar
24. Roles in PHP variable• All variables in PHP are denoted with a leading dollar sign ($).
• The value of a variable is the value of its most recent
assignment.
• Variables are assigned with the = operator, with the variable
on the left-hand side and the expression to be evaluated on
the right.
• Variables can, but do not need, to be declared before
assignment.
• Variables in PHP do not have intrinsic types - a variable does
not know in advance whether it will be used to store a
number or a string of characters.
• Variables used before they are assigned have default values.
• PHP does a good job of automatically converting types from
one to another when necessary.
• PHP variables are Perl-like.
M.S. Chahar
25. Data Type in PHP
• PHP has a total of Eight data types :
• Integers: are whole numbers, without a decimal point, like
4195.
• Doubles: are floating-point numbers, like 3.14159 or 49.1.
• Booleans: have only two possible values either true or false.
• NULL: is a special type that only has one value: NULL.
• Strings: are sequences of characters, like 'PHP supports string
operations.'
• Arrays: are named and indexed collections of other values.
• Objects: are instances of programmer-defined classes, which
can package up both other kinds of values and functions that
are specific to the class.
• Resources: are special variables that hold references to
resources external to PHP (such as database connections).M.S. Chahar
26. • PHP Constants
• A constant is a name or an identifier for a
simple value. A constant value cannot change
during the execution of the script.
• A constant you have to use define() function.
M.S. Chahar
27. constant() example:
• <?php
•
• define("MINSIZE", 50);
•
• echo MINSIZE;
• echo constant("MINSIZE"); // same thing as the
previous line
•
• ?>
M.S. Chahar
28. Differences between constants and
variables are:
• There is no need to write a dollar sign ($) before
a constant, where as in Variable one has to write
a dollar sign.
• Constants cannot be defined by simple
assignment, they may only be defined using the
define() function.
• Constants may be defined and accessed
anywhere without regard to variable scoping
rules.
• Once the Constants have been set, may not be
redefined or undefined.
M.S. Chahar
30. PHP Decision Making
• The if, elseif ...else and switch statements are
used to take decision based on the different
condition.
• if...else statement - use this statement if you
want to execute a set of code when a
condition is true and another if the condition
is not true
M.S. Chahar
Syntax
if (condition)
code to be executed if condition is true;
else
code to be executed if condition is false;
31. Ex….
• <html>
• <body>
• <?php
• $d=date("D");
• if ($d=="Fri")
• echo "Have a nice weekend!";
• else echo "Have a nice day!"; ?>
• </body>
• </html>
M.S. Chahar
32. • elseif statement - is used with the if...else
statement to execute a set of code if one of
several condition are true
M.S. Chahar
Syntax
if (condition)
code to be executed if condition is true;
elseif (condition)
code to be executed if condition is true;
else
code to be executed if condition is false;
34. • switch statement - is used if you want to
select one of many blocks of code to be
executed, use the Switch statement. The
switch statement is used to avoid long blocks
of if..elseif..else code.
M.S. Chahar
Syntax
switch (expression)
{
case label1:
code to be executed if expression = label1;
break;
case label2:
code to be executed if expression = label2;
break;
default:
code to be executed
if expression is different
from both label1 and label2;
}
35. • <html> <body> <?php $d=date("D");
switch ($d) { case "Mon": echo "Today is
Monday"; break; case "Tue": echo
"Today is Tuesday"; break; case "Wed":
echo "Today is Wednesday"; break; case
"Thu": echo "Today is Thursday"; break;
case "Fri": echo "Today is Friday"; break;
case "Sat": echo "Today is Saturday";
break; case "Sun": echo "Today is
Sunday"; break; default: echo "Wonder
which day is this ?"; } ?> </body>
</html> M.S. Chahar
36. PHP Loop Types
• PHP are used to execute the same block of
code a specified number of times. PHP
supports following four loop types.
• for -
• while -
• do...while -
• foreach - loops through a block of code for
each element in an array.
M.S. Chahar
37. • The foreach loop statement
• The foreach statement is used to loop through
arrays. For each pass the value of the current
array element is assigned to $value and the
array pointer is moved by one and in the next
pass next element will be processed.
M.S. Chahar
39. Example foreach loop
M.S. Chahar
<html>
<body>
<?php
$array=array(1,2,3,4,5);
foreach($arrayas$value)
{
echo"Valueis$value<br/>";
}
?>
</body>
</html>
40. PHP Arrays
• An array is a data structure that stores one or
more similar type of values in a single value.
• For example if you want to store 100 numbers
then instead of defining 100 variables its easy
to define an array of 100 length.
M.S. Chahar
41. • There are three different kind of arrays and
each array value is accessed using an ID c
which is called array index.
– Numeric array - An array with a numeric index.
Values are stored and accessed in linear fashion
– Associative array - An array with strings as index.
This stores element values in association with key
values rather than in a strict linear index order.
– Multidimensional array - An array containing one
or more arrays and values are accessed using
multiple indices
M.S. Chahar
42. Numeric Array
• These arrays can store numbers, strings and
any object but their index will be
prepresented by numbers. By default array
index starts from zero.
M.S. Chahar
44. Associative Arrays
• The associative arrays are very similar to
numeric arrays in term of functionality but
they are different in terms of their index.
Associative array will have their index as string
so that you can establish a strong association
between key and values.
• Ex ass.php
M.S. Chahar
45. Multidimensional Arrays
• A multi-dimensional array each element in the
main array can also be an array. And each
element in the sub-array can be an array, and
so on. Values in the multi-dimensional array
are accessed using multiple index.
M.S. Chahar
46. PHP Strings
• They are sequences of characters, like "PHP
supports string operations".
M.S. Chahar
47. There are valid examples of string
• $string_1 = "This is a string in double quotes";
• $string_2 = "This is a somewhat longer, singly
quoted string";
• $string_39 = "This string has thirty-nine
characters";
• $string_0 = ""; // a string with zero characters
M.S. Chahar
49. The escape-sequence
replacements are:
• n is replaced by the newline character
• r is replaced by the carriage-return character
• t is replaced by the tab character
• $ is replaced by the dollar sign itself ($)
• " is replaced by a single double-quote (")
• is replaced by a single backslash ()
M.S. Chahar
50. PHP File Inclusion
• You can include the content of a PHP file into
another PHP file before the server executes it.
• There are two PHP functions which can be
used to included one PHP file into another
PHP file.
• The include() Function
• The require() Function
M.S. Chahar
51. • This is a strong point of PHP which helps in
creating functions, headers, footers, or
elements that can be reused on multiple
pages. This will help developers to make it
easy to change the layout of complete website
with minimal effort.
M.S. Chahar
52. The include() Function
• The include() function takes all the text in a
specified file and copies it into the file that
uses the include function. If there is any
problem in loading a file then the include()
function generates a warning but the script
will continue execution.
• you want to create a common menu for your
website. Then create a file ex.php.
M.S. Chahar
53. The require() Function
• The require() function takes all the text in a
specified file and copies it into the file that
uses the include function. If there is any
problem in loading a file then the require()
function generates a fatal error and halt the
execution of the script.
M.S. Chahar
54. • So there is no difference in require() and
include() except they handle error conditions.
It is recommended to use the require()
function instead of include(), because scripts
should not continue executing if files are
missing or misnamed.
M.S. Chahar
55. PHP Files & I/O
• Following functions related to files:
• Opening a file
• Reading a file
• Writing a file
• Closing a file
M.S. Chahar
56. • Opening and Closing Files
• PHP fopen() function is used to open a file. It
requires two arguments stating first the file
name and then mode in which to operate.
M.S. Chahar
57. Files modes can be specified as one of the
six options in this table.
M.S. Chahar
Mode Purpose
r
Opens the file for reading only.
Places the file pointer at the beginning of the file.
r+
Opens the file for reading and writing.
Places the file pointer at the beginning of the file.
w
Opens the file for writing only.
Places the file pointer at the beginning of the file.
and truncates the file to zero length. If files does not
exist then it attemts to create a file.
w+
Opens the file for reading and writing only.
Places the file pointer at the beginning of the file.
and truncates the file to zero length. If files does not
exist then it attemts to create a file.
a
Opens the file for writing only.
Places the file pointer at the end of the file.
If files does not exist then it attemts to create a file.
a+
Opens the file for reading and writing only.
Places the file pointer at the end of the file.
If files does not exist then it attemts to create a file.
58. • If an attempt to open a file fails then fopen
returns a value of false otherwise it returns a
file pointer which is used for further reading
or writing to that file.
• After making a changes to the opened file it is
important to close it with the fclose()
function. The fclose() function requires a file
pointer as its argument and then returns true
when the closure succeeds or false if it fails.
M.S. Chahar
59. Reading a file
• Once a file is opened using fopen() function it
can be read with a function called fread(). This
function requires two arguments. These must
be the file pointer and the length of the file
expressed in bytes.
• The files's length can be found using the
filesize() function which takes the file name as
its argument and returns the size of the file
expressed in bytes.
M.S. Chahar
60. • So here are the steps required to read a file
with PHP.
• Open a file using fopen() function.
• Get the file's length using filesize() function.
• Read the file's content using fread() function.
• Close the file with fclose() function.
• Example:File.php
M.S. Chahar
61. Writing a file
• A new file can be written or text can be
appended to an existing file using the PHP
fwrite() function. This function requires two
arguments specifying a file pointer and the
string of data that is to be written. Optionally
a third integer argument can be included to
specify the length of the data to write. If the
third argument is included, writing would will
stop after the specified length has been
reached. M.S. Chahar
62. PHP Cookies
• Cookies are text files stored on the client
computer and they are kept of use tracking
purpose.
M.S. Chahar
63. • There are three steps involved in identifying
returning users:
• Server script sends a set of cookies to the
browser. For example name, age, or
identification number etc.
• Browser stores this information on local
machine for future use.
• When next time browser sends any request to
web server then it sends those cookies
information to the server and server uses that
information to identify the user.
M.S. Chahar
