Description:

PHP4 is an HTML-embeddable scripting language. PHP offers built-in database
integration for several commercial and non-commercial database management
systems, so writing a database-enabled script with PHP is fairly simple. The
most common use of PHP coding is probably as a replacement for CGI scripts.

You can build php4 with some conditional build swithes;

(ie. use with rpm --rebuild):
--with[out] debug Compile with debugging code
--with[out] hardened Compile with the Hardened-PHP patch applied (disabled)
you will have to rebuild all php-* extensions against
the Hardened-PHP, and also live with the fact that
commercial extensions will not work anymore :(
