PHP Introduction


PHP is a scripting language embedded in HTML.

PHP stands for Personal Home Page (old full form).

PHP now stands for PHP Hypertext Preprocessor.

PHP is used to create dynamic web pages.

PHP documents end with .php extension.

Used for server side scripting.

PHP can be embedded with html.

PHP is open source.

PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server, generating HTML which is then sent to the client. The client would receive the results of running that script, but would not know what the underlying code was. You can even configure your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve.

The best things in using PHP are that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Don't be afraid reading the long list of PHP's features. You can jump in, in a short time, and start writing simple scripts in a few hours.

Format of PHP program

• PHP documents end with the extension .php .

• When a web server encounters this extension in a requested file, it automatically passes it to the PHP processor.
