PHP and MYSQL 



Introduction: 
PHP started out as a small open source project that evolved as more and more people found out how
 useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994.
 PHP is a recursive acronym for "PHP: Hypertext Preprocessor". 
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, executeseven 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 andCORBA), making n-tier 
development a possibility for the first time.
PHP   is forgiving: PHP language tries to be as forgiving as possible.
