PHP has, in just a few short years, become one of the predominant
scripting languages on the web. It's another integral element of LAMP
development, and can be found everywhere from personal homepages to
content management systems (such as Drupal) to
large-scale corporate intranets. With a relatively easy syntax and open
source licensing, webmasters and developers around the world have
migrated to PHP from the more difficult and syntactically challenging
scripting languages like Perl.
