Course Description

What is PHP?

PHP is a server side scripting language. that is used to develop Static websites or Dynamic websites or Web applications. PHP stands for Hypertext Pre-processor, that earlier stood for Personal Home Pages. PHP scripts can only be interpreted on a server that has PHP installed. The client computers accessing the PHP scripts require a web browser only. A PHP file contains PHP tags and ends with the extension “.php”.

  • PHP stands for Hypertext Preprocessor.
  • As we said before it is a server-side scripting language.
  • PHP is free and is an open source software product.
  • The PHP scripts are executed on the server.
  • PHP supports many databases (MySQL, Sybase, Oracle and many others.)
  • PHP runs on different platforms (Unix, Linux, Windows.)
  • PHP is compatible with almost all web-servers used today (Apache, IIS, etc.)
  • A PHP file can contain plain text, HTML tags and scripts
  • The PHP files can have one of the following extensions: php, php3 or phtml.

 What do you need?

Before learning PHP Programming you need to have the following:

  1. Access to a web server (like Apache)
  2. PHP and MySQL should be installed on the web server
  • The easiest way is to find a cheap web hosting plan that support PHP and MySQL (most of the web-hosting providers do.) For a couple of bucks a month you can get a virtual host. The advantage is that everything is already installed and that you can share your program (that you are going to write) with the rest of the world.
  • If you don’t want to spend money, you can also install everything on your local machine. The easiest way is to install WAMP if you have a Windows machine and LAMP if you have a Linux machine. (WAMP = Windows Apache MySQL PHP and LAMP = Linux Apache MySQL PHP.) These packages install everything you need. Read the install manual of these packages for instructions. After installation you should have access to http://localhost in your browser.

Advantages of PHP

  • Open source: It is developed and maintained by a large group of PHP developers, this will helps in creating a support community, abundant extension library.
  • Speed: It is relative fast since it uses much system resource.
  • Easy to use: It uses C like syntax, so for those who are familiar with C, it’s very easy for them to pick up and it is very easy to create website scripts.
  • Stable: Since it is maintained by many developers, so when bugs are found, it can be quickly fixed.
  • Powerful library support: You can easily find functional modules you need such as PDF, Graph etc.
  • Built-in database connection modules: You can connect to database easily using PHP, since many websites are data/content driven, so we will use database frequently, this will largely reduce the development time of web apps.
  • Can be run on many platforms, including Windows, Linux and Mac, it’s easy for users to find hosting service providers.

Disadvantages of PHP

  • Not suitable for large applications: Hard to maintain since it is not very modular.
  • Weak type:  Implicit conversion may surprise unwary programmers and lead to unexpected bugs. For example, the strings “1000” and “1e3” compare equal because they are implicitly cast to floating point numbers
