LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
2. What we'll cover
• A short history of php
• Parsing
• Variables
• Arrays
• Operators
• Functions
• Control Structures
• External Data Files
Nikul Shah 2
3. Background
• PHP is server side scripting system
• PHP stands for "PHP: Hypertext Preprocessor"
• Syntax based on Perl, Java, and C
• Very good for creating dynamic content
• Powerful, but somewhat risky!
• If you want to focus on one system for dynamic
content, this is a good one to choose
Nikul Shah 3
4. History
• Started as a Perl hack in 1994 by Rasmus Lerdorf
(to handle his resume), developed to PHP/FI 2.0
• By 1997 up to PHP 3.0 with a new parser engine
by Zeev Suraski and Andi Gutmans
• Version 5.2.4 is current version, rewritten by Zend
(www.zend.com) to include a number of features,
such as an object model
• Current is version 5
• php is one of the premier examples of what an
open source project can be
Nikul Shah 4
5. About Zend
• A Commercial Enterprise
• Zend provides Zend engine for PHP for free
• They provide other products and services for a fee
• Server side caching and other optimizations
• Encoding in Zend's intermediate format to protect
source code
• IDE-a developer's package with tools to make life
easier
• Support and training services
• Zend's web site is a great resource
Nikul Shah 5
6. PHP 5 Architecture
• Zend engine as parser (Andi Gutmans and Zeev Suraski)
• SAPI is a web server abstraction layer
• PHP components now self contained (ODBC, Java,
LDAP, etc.)
• This structure is a good general design for software
(compare to OSI model, and middleware applications)

7. PHP Scripts
• Typically file ends in .php--this is set by the web
server configuration
• Separated in files with the <?php ?> tag
• php commands can make up an entire file, or can
be contained in html--this is a choice….
• Program lines end in ";" or you get an error
• Server recognizes embedded script and executes
• Result is passed to browser, source isn't visible
<P>
<?php $myvar = "Hello World!";
echo $myvar;
?>
</P> Nikul Shah 7
8. Parsing
• Breaking a data block into smaller chunks by
following a set of rules, so that it can be more
easily interpreted, managed, or transmitted by a
computer. Spread sheet programs, for example,
parse a data to fit it into a cell of certain size.
Nikul Shah 8
9. Parsing
• We've talk about how the browser can read a text
file and process it, that's a basic parsing method
• Parsing involves acting on relevant portions of a
file and ignoring others
• Browsers parse web pages as they load
• Web servers with server side technologies like php
parse web pages as they are being passed out to
the browser
• Parsing does represent work, so there is a cost
Nikul Shah 9
10. Two Ways
• You can embed sections of php inside html:
• Or you can call html from php:
<BODY>
<P>
<?php $myvar = "Hello World!";
echo $myvar;
</BODY>
<?php
echo "<html><head><title>Howdy</title>
…
?>
Nikul Shah 10
11. Variables
• Typed by context (but one can force type), so it's
loose
• Begin with "$" (unlike javascript!)
• Assigned by value
• $foo = "Bob"; $bar = $foo;
• Assigned by reference, this links vars
• $bar = &$foo;
• Some are preassigned, server and env vars
• For example, there are PHP vars, eg. PHP_SELF,
HTTP_GET_VARS 00
Nikul Shah 11
12. phpinfo()
• The phpinfo() function shows the php
environment
• Use this to read system and server variables,
setting stored in php.ini, versions, and
modules
• Notice that many of these data are in arrays
• This is the first script you should write…
00_phpinfo.php
Nikul Shah 12
13. Variable Variables
• Using the value of a variable as the name of
a second variable)
$a = "hello";
$$a = "world";
• Thus:
echo "$a ${$a}";
• Is the same as:
echo "$a $hello";
• But $$a echoes as "$hello"….
00_hello_world.php
Nikul Shah 13
14. Operators
• Arithmetic (+, -, *, /, %) and String (.)
• Assignment (=) and combined assignment
$a = 3;
$a += 5; // sets $a to 8;
$b = "Hello ";
$b .= "There!"; // sets $b to "Hello There!";
• Bitwise (&, |, ^, ~, <<, >>)
• $a ^ $b (Xor: Bits that are set in $a or $b but not both are set.)
• ~ $a (Not: Bits that are set in $a are not set, and vice versa.)
• Comparison (==, ===, !=, !==, <, >, <=, >=)
Nikul Shah 14
15. Coercion
• Just like JavaScript, php is loosely typed
• Coercion occurs the same way
• If you concatenate a number and string, the
number becomes a string
Nikul Shah 15
16. Operators: The Movie
• Error Control (@)
• When this precedes a command, errors generated are ignored
(allows custom messages)
• Execution (` is similar to the shell_exec()
function)
• You can pass a string to the shell for execution:
$output = `ls -al`;
$output = shell_exec("ls -al");
• This is one reason to be careful about user set variables!
• Incrementing/Decrementing
++$a (Increments by one, then returns $a.)
$a++ (Returns $a, then increments $a by one.)
--$a (Decrements $a by one, then returns $a.)
$a-- (Returns $a, then decrements $a by one.)
Nikul Shah 16
17. Son of the Valley of Operators
• Logical
$a and $b And True if both $a and $b are true.
$a or $b Or True if either $a or $b is true.
$a xor $b Xor True if either $a or $b is true,
but not both.
! $a Not True if $a is not true.
$a && $b And True if both $a and $b are true.
$a || $b Or True if either $a or $b is true.
• The two ands and ors have different
precedence rules, "and" and "or" are lower
precedence than "&&" and "||"
• Use parentheses to resolve precedence
problems or just to be clearer
Nikul Shah 17
18. String operator
• . Is a concatenation operator.
• Example
• <?php
$txt1 = “Nikul";
$txt2 = " Shah!";
echo $txt1 . $txt2;
?>
Nikul Shah 18
20. Variables: What are they?
• When we work in PHP, we often need a
labelled place to store a value (be it a string,
number, whatever) so we can use it in
multiple places in our script.
• These labelled ‘places’ are called
VARIABLES
Nikul Shah 20
21. Variables: Naming
• $ followed by variable name
• Case sensitive
• $variable differs from $Variable
• Stick to lower-case to be sure!
• Name must started with a letter or an
underscore
• Followed by any number of letters, numbers
and underscores
Nikul Shah 21
24. Control Structures
• Wide Variety available
• if, else, elseif
• while, do-while
• for, foreach
• break, continue, switch
• require, include, require_once, include_once
Nikul Shah 24
25. If, Else
• <?php
$t = date("H");
if ($t < "20") {
echo "Have a good day!";
} else {
echo "Have a good night!";
}
?>
Nikul Shah 25
26. The if, elseif, else
• 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;
}
Nikul Shah 26
27. if, elseif, else example
if ($i == 0) {
echo "i equals 0";
} elseif ($i == 1) {
echo "i equals 1";
} elseif ($i == 2) {
echo "i equals 2";
}
Nikul Shah 27
28. Control Structures
• Mostly parallel to what we've covered
already in javascript
• if, elseif, else, while, for, foreach, break and
continue
Nikul Shah 28
29. Switch
• Switch, which we've seen, is very useful
• These two do the same
things….
switch ($i) {
case 0:
echo "i equals 0";
break;
case 1:
echo "i equals 1";
break;
case 2:
echo "i equals 2";
break;
}
Nikul Shah 29
30. While
• while (condition is true)
{
code to be executed;
}
• Example
<?php $x = 1;
while($x <= 5) {
echo "The number is: $x
<br>";
$x++;
}
?>
Nikul Shah 30
31. Do while.
• do {
code to be executed;
} while (condition is
true);
• <?php
$x = 1;
do {
echo "The number
is: $x <br>";
$x++;
} while ($x <= 5);
?>
Nikul Shah 31
32. For Loop
for (init counter; test
counter; increment
counter) {
code to be executed;
}
• <?php
for ($x = 0; $x <= 10;
$x++) {
echo "The number
is: $x <br>";
}
?>
Nikul Shah 32
33. foreach Loop
• foreach ($array as
$value) {
code to be executed;
}
• <?php
$colors = array("red",
"green", "blue",
"yellow");
foreach ($colors as
$value) {
echo "$value <br>";
}
?>
Nikul Shah 33
34. Constants
• Constants (unchangeable variables) can also
be defined.
• Each constant is given a name (note no
preceding dollar is applied here).
• By convention, constant names are usually
in UPPERCASE.
Nikul Shah 34
35. “ or ‘ ?
• There is a difference between strings
written in single and double quotes.
• In a double-quoted string any variable
names are expanded to their values.
• In a single-quoted string, no variable
expansion takes place.
Nikul Shah 35
36. Example: A Dynamic Table
• I hate writing html tables
• You can build one in php
• This example uses pictures and builds a
table with pictures in one column, and
captions in another
• The captions are drawn from text files
• I'm using tables, but you could use css for
placement easily…
Nikul Shah 36
37. Arrays
• You can create an array with the array function, or use the
explode function (this is very useful when reading files into
web programs…)
$my_array = array(1, 2, 3, 4, 5);
$pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
• An array is simply a variable representing a keyed list
• A list of values or variables
• If a variable, that var can also be an array
• Each variable in the list has a key
• The key can be a number or a text labelNikul Shah 37
38. • Arrays are lists, or lists of lists, or list of lists of
lists, you get the idea--Arrays can be multi-
dimensional
• Array elements can be addressed by either by
number or by name (strings)
• If you want to see the structure of an array, use the
print_r function to recursively print an array inside
of pre tags
Arrays
Nikul Shah 38
39. Text versus Keys
• Text keys work like number keys (well,
really, it's the other way around--number
keys are just labels)
• You assign and call them the same way,
except you have to assign the label to the
value or variables, eg:
echo "$my_text_array[third]";
$my_text_array = array(first=>1, second=>2, third=>3);
echo "<pre>";
print_r($my_text_array);
echo "</pre>";
Nikul Shah 39
40. Walking Arrays
• Use a loop, eg a foreach loop to walk
through an array
• while loops also work for arrays with
numeric keys--just set a variable for the
loop, and make sure to increment that
variable within the loop
$colors = array('red', 'blue', 'green', 'yellow');
foreach ($colors as $color) {
echo "Do you like $color?n";
}
05_arrays.php
Nikul Shah 40
41. 05_arrays.php
• You can't echo an
array directly…
• You can walk through
an echo or print() line
by line
• You can use print_r(),
this will show you the
structure of complex
arrays--that output is
to the right, and it's
handy for learning the
structure of an array
Array
(
[1] => Array
(
[sku] => A13412
[quantity] => 10
[item] => Whirly Widgets
[price] => .50
)
[2] => Array
(
[sku] => A43214
[quantity] => 142
[item] => Widget Nuts
[price] => .05
)
Nikul Shah 41
42. Multidimensional Arrays
• A one dimensional array is a list, a spreadsheet or other columnar data
is two dimensional…
• Basically, you can make an array of arrays
$multiD = array
(
"fruits" => array("myfavorite" => "orange", "yuck" => "banana", "yum" => "apple"),
"numbers" => array(1, 2, 3, 4, 5, 6),
"holes" => array("first", 5 => "second", "third")
);
• The structure can be built array by array, or declared with a single
statement
• You can reference individual elements by nesting:
echo "<p>Yes, we have no " . $multiD["fruits"]["yuck"] . " (ok by me).</p>";
• print_r() will show the entire structure, but don’t forget the pre tags
01a_arrays.php
Nikul Shah 42
43. Getting Data into arrays
• You can directly read data into individual
array slots via a direct assignment:
$pieces[5] = "poulet resistance";
• From a file:
• Use the file command to read a delimited file
(the delimiter can be any unique char):
$pizza = file(./our_pizzas.txt)
• Use explode to create an array from a line
within a loop:
$pieces = explode(" ", $pizza);
Nikul Shah 43
44. The Surface
• The power of php lies partially in the wealth of
functions---for example, the 40+ array functions
• array_flip() swaps keys for values
• array_count_values() returns an associative array of all
values in an array, and their frequency
• array_rand() pulls a random element
• array_unique() removes duppies
• array_walk() applies a user defined function to each
element of an array (so you can dice all of a dataset)
• count() returns the number of elements in an array
• array_search() returns the key for the first match in an
array
08_array_fu.php
Nikul Shah 44
45. Using External Data
• You can build dynamic pages with just the
information in a php script
• But where php shines is in building pages
out of external data sources, so that the web
pages change when the data does
• Most of the time, people think of a database
like MySQL as the backend, but you can
also use text or other files, LDAP, pretty
much anything….
Nikul Shah 45
46. Standard data files
• Normally you'd use a tab delimited file, but you can
use pretty much anything as a delimiter
• Files get read as arrays, one line per slot
• Remember each line ends in n, you should clean
this up, and be careful about white space
• Once the file is read, you can use explode to break
the lines into fields, one at a time, in a loop….
Nikul Shah 46
47. Standard data files
• You can use trim() to clean white space and
returns instead of str_replace()
• Notice that this is building an array of arrays
$items=file("./mydata.txt");
foreach ($items as $line)
{
$line = str_replace("n", "", $line);
$line = explode("t", $line);
// do something with $line array
} Nikul Shah 47
49. 06_more_arrays.php
• This is a simple script to read and process a text
file
• The data file is tab delimited and has the column
titles as the first line of the file
Nikul Shah 49
50. How it works
• The script uses the first line to build text labels for
the subsequent lines, so that the array elements can
be called by the text label
• If you add a new column, this script
compensates
• Text based arrays are not position dependent…
• This script could be the basis of a nice function
• There are two version of this, calling two different
datafiles, but that's the only difference
Nikul Shah 50
52. Alternative syntax
• Applies to if, while, for, foreach, and switch
• Change the opening brace to a colon
• Change the closing brace to an endxxx
statement
sample code from http://us3.php.net/manual/en/control-structures.alternative-syntax.php
<?php if ($a == 5): ?>
A is equal to 5
<?php endif; ?>
<?php
if ($a == 5):
echo "a equals 5";
echo "...";
else:
echo "a is not 5";
endif;
?> 07
