What is PHP ?


PHP is a general purpose scripting language that is especially suited to server-side web development where php generally run on a web serve.

PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content

PHP is also used for command line scripting and client-side GUI application

PHP can be deployed on most web servers, many operating systems and platforms, and xan be used with many relation database management systems.


<html> <head><title> PHP Test </title> </head> <body> <?php echo “Hello World”; ?> </body>


PHP is only parses code within its delimiters. Anything outside its delimiters is sent directly to the output and is not processed by PHP.

The most common delimiters are <? Php to open and ?> <script language=“php”> </script> <?= ( which is used to echo back to string or variable) and ?> < % or < % = and %>

Here the Out put is “Hello World”.


PHP stores whole numbers in platform-dependent range.

This range is typically that of 32-bit signed integers. Unsigned integer are converted to signed value in certain situation.

Arrays can contain element of any type that handle in PHP

Include resources, objects and even other arrays

PHP also supports strings which can be used with single quotes, or heredoc syntax.


PHP script are stored as human readable source code and are compiled on-the-fly to an internal format that can be executed by the PHP engine

Code optimizers aim to reduce the runtime of the complied code by reducing its size and making other changes that can reduce the execution time with the goal of improving performance.


PHP include free and open source libraries PHP is a fundamentally internet aware system Many database servers, embedded SQL

libraries such as embedded postgre SQL, MySQL and SQLite, LDAP servers, and others.

PHP allows developers to write extensions in C to add functionality to the PHP language

These can than be compiled into PHP or loaded dynamically at runtime.
