links the Perl runtime library into the server and provides an object-

oriented Perl interface for the Apache server’s C language Applica-

tion Programming Interface (API). The end result is a quicker CGI

script turnaround process, since no external Perl interpreter has to

be started.

The most common use of mod perl is the use of its Apache::Registry

module as aspeedy replacementfor the Common Gateway Interface

(CGI).The Apache::Registrymodule emulatesthe CGIenvironment,

so programmers can write CGI scripts which will run under either

CGI or mod perl.

You should realize that previously existing CGI scripts may require

some improvements. Normally, CGI scripts have a lifetime of one

HTTP request. That short lifespan allows programmers to get away

withquestionablescripting. Sincethe Apache::Registrymodulemain-

tains a cache of scripts, it is quicker, but it may be less forgiving of

non-standard programming.

forCGI, referto section 4.2on page78. For moregeneralinformation

Description: PHP is an HTML-embedded scripting language. PHP at-

tempts to make it easy for developers to write dynamically gener-

ated web pages. PHP also offers built-in database integration for

several commercial and non-commercial database management sys-

tems, so writing a database-enabled web page with PHP is fairly

simple. The most common use of PHP coding is probably as a re-

placement for CGI scripts.

The mod php module enables the Apache web server to understand

and process the embeddedPHP language in webpages. Please refer
