The term PHP is an acronym for PHP: Hypertext Preprocessor. PHP is a server-side scripting language designed specifically for web development.Websites like www.facebook.com, www.yahoo.com are also built on PHP. One of the main reason behind this is that PHP can be easily embedded in HTML files and HTML codes can also be written in a PHP file.
Features Of PHP
PHP is a server side scripting language that is embedded in HTML. It is used to manage
dynamic content, databases, session tracking, even build entire e-commerce sites.
It is integrated with a number of popular databases, including MySQL, PostgreSQL,
Oracle, Sybase, Informix, and Microsoft SQL Server.
PHP is pleasingly zippy in its execution, especially when compiled as an Apache module
on the Unix side. The MySQL server, once started, executes even very complex queries
with huge result sets in record-setting time.
PHP supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4
added support for Java and distributed object architectures (COM and CORBA), making
n-tier development a possibility for the first time.
PHP is forgiving: PHP language tries to be as forgiving as possible.
