Many of the world's popular Blogs and CMS (Content Management Systems) such as WordPress, Drupal and Joomla are built on PHP. e. PHP scripts (codes) are in plain-text and human readable. When a browser views a php page, the webserver has to send the request to the PHP engine to interpret/execute the codes and return the results back to the Apache webserver. The webserver then displays the results in ‘html’ to the user (webrowser). This 2-way communication between the webserver and PHP engine is done via the PHP SAPI (Server API) and Apache Handler.
Handlers can either be 'built-in' or included in a module. The standard built-in Apache handlers are: default-handler (core) send-as-is (mod_asis) cgi-script (mod_cgi) imap-file (mod_imagemap) server-info (mod_info) server-status (mod_status) type-map (mod_negotiation) Generally, files have implicit handlers, based on the file type. Most files are served by Apache itself, but scripts such as php, perl, python, etc have their own specific handlers because Apache needs to communicate with those ‘external’ application servers.
