While the success of Open Source software like Linux or Apache has been documented
extensively throughout all mainstream media, the rise of PHP has gone largely
unnoticed. Still, the Web scripting language PHP is the most popular module for the
Apache Web server, according to an E-Soft survey (www.e-softinc.com/survey/).
Netcraft studies have found that PHP is in use on over 6% of all Web domains in the
world (see www.netcraft.com/survey).That’s an incredible market penetration for a
rather specialized product.This popularity continues to rise exponentially. Increasingly,
this is being reflected in traditional media: As of May, 2000, more than 20 books about
PHP have been published in different languages, with more in the pipeline.
Commercial players are beginning to join the bandwagon: PHP is included with
Web servers, for example C2’s Stronghold, and Linux distributions. A new company,
Zend Technologies, has been formed to provide commercial add-ons and support for
PHP.A long list of large-scale Web sites employ PHP, as well as hundreds of thousands
of small to medium Web sites.
