Which PHP Module Should You Choose?
Within each version of mod_php4 and mod_php3,
there are several "builds" to choose from. A build consists of PHP's core features--which are found in
every build--and some optional additional features, such as database
support, on-the-fly image creation, and encryption. You should choose
the build that best suits your needs but at the same time does not add
unnecessary overhead to your web server.
For example, if you plan on making use of PHP to transfer files
between computers, or to use
to access your email, you'll want to
choose a PHP build that includes
imap, and the database
mSQL) you're using for TWIG in the build name.
If you want to use PHP chiefly to access a PostgreSQL database, but not build images on
the fly, choose a PHP build with
pgsql but without
gd in the build name.
By selecting the PHP build carefully, you will maximize your virtual
server's memory use as well as improve the performance of your
Apache Web Server.
