PHP Introduction: What is PHP ? |
PHP is a server side scripting language, widely used in internet programming.

interact with database servers and manage the page content accordingly. The
difference between a static page like HTML and dynamic page like PHP is the way
the server interpret the request. Let us take one simple example.

Installation overview
When ever request comes for a static html or
htm page the web server returns the page to the client. Here script
processing or execution is not done. Such pages don't have dynamic
capability and content is fixed. In Windows server the web server is IIS and for Linux systems Apache web servers are generally used. However PHP and Apache runs well in Windows platform also. This site is supporting PHP on a Linux platform. In the same way the server can run other scripts like ASP, Perl etc. PHP can be downloaded from www.php.net
Incase of PHP pages the server does not return
the page directly to the client. The web server runs the PHP engine and
the output of the executed script is posted back to the client
machine. Depending on the various input conditions the page content
can be changed. PHP can easily connect to MySQL database and this combination is very popular in the internet
