 PHP5 is an HTML-embedded scripting language. Much of its syntax is borrowed
 from C, Java and Perl with a couple of unique PHP-specific features thrown
 in. The goal of the language is to allow web developers to write dynamically
 generated pages quickly. This version of PHP5 was built with the Suhosin patch.
