PHP is a general purpose scripting language that is commonly used for web development. It allows developers to embed PHP code into HTML pages in order to create dynamic content and applications. PHP code is processed on the server side, allowing it to interact with databases, sessions, and other backend systems to dynamically generate content for users. Some common uses of PHP include creating dynamic websites, manipulating content on web pages, and interacting with databases through server-side scripts.
Brief History of PHP
PHP (PHP: Hypertext Preprocessor) was created by Rasmus Lerdorf in 1994. It was initially developed for HTTP usage logging and server-side form generation in Unix.
PHP 2 (1995) transformed the language into a Server-side embedded scripting language. Added database support, file uploads, variables, arrays, recursive functions, conditionals, iteration, regular expressions, etc.
PHP 3 (1998) added support for ODBC data sources, multiple platform support, email protocols (SNMP,IMAP), and new parser written by Zeev Suraski and Andi Gutmans .
PHP 4 (2000) became an independent component of the web server for added efficiency. The parser was renamed the Zend Engine. Many security features were added.
PHP 5 (2004) adds Zend Engine II with object oriented programming, robust XML support using the libxml2 library, SOAP extension for interoperability with Web Services, SQLite has been bundled with PHP
What is PHP Used For?
PHP is a general-purpose server-side scripting language originally designed for web development to produce dynamic web pages
PHP can interact with MySQL databases
What is PHP?
PHP == ‘Hypertext Preprocessor’
Open-source, server-side scripting language
Used to generate dynamic web-pages
PHP scripts reside between reserved PHP tags
This allows the programmer to embed PHP scripts within HTML pages
What is PHP (cont’d)
Interpreted language, scripts are parsed at run-time rather than compiled beforehand
Executed on the server-side
Source-code not visible by client
‘View Source’ in browsers does not display the PHP code
Various built-in functions allow for fast development
Compatible with many popular databases
What does PHP code look like?
Structurally similar to C/C++
Supports procedural and object-oriented paradigm (to some degree)
All PHP statements end with a semi-colon
Each PHP script must be enclosed in the reserved PHP tag
Comments in PHP
Standard C, C++, and shell comment symbols
Variables in PHP
PHP variables must begin with a “$” sign
Case-sensitive ($Foo != $foo != $fOo)
Global and locally-scoped variables
Global variables can be used anywhere
Local variables restricted to a function or class
Certain variable names reserved by PHP
Form variables ($_POST, $_GET)
Server variables ($_SERVER)
Etc.
Variable usage
Arithmetic Operations
$a - $b // subtraction
$a * $b // multiplication
$a / $b // division
$a += 5 // $a = $a+5 Also works for *= and /=
Concatenation
Use a period to join strings into one.
If ... Else...
If (condition)
{
Statements;
}
Else
{
Statement;
}
While Loops
While (condition)
{
Statements;
}
Date Display
$datedisplay=date(“yyyy/m/d”);
Print $datedisplay;
# If the date is April 1st, 2009
# It would display as 2009/4/1

This is a presentation for my coursework of Advanced Nutrition Course that have been presented in 2009/2010 when I was in university. We have to review any fad diet book and I chose The French Don't Diet Book. As you may know, certain fad diets offer false claims.
But from my reading, I can say that this book may help those who wants to lose weight, without dieting.
Now, after a few months, I would like to share this to everyone. So I re-edited AND uploaded them here. You may notice that certain slides are designed very conservatively. This is because it is presented in an educational and academical environment. Thus, it is unavoidable
How To Feel Confident: The Cutiez Way is a compilation of Confidence Booster which you can read from a book 'How To Feel Confident: Simple Tools for Instant Success' by Leil Lowndes.
The writer summaries the tips and tricks of the book in Confidence Booster. Those who are shy will be shock when reading this book because it explained what we've experienced as a shy precisely. I find it very useful and would like to share it with others, in a simple way. So I hope everyone can gain something from this slide. More to come in the future because Confidence Booster have >60 tips altogether

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
