PHP has several built-in functions for dealing with regular expressions. We'll examine only the PCRE functions (preg_replace, preg_match_all), which use a Perl-compatible regular expression syntax, as they are often faster than POSIX alternatives (ereg, ereg_replace, etc.)..

The following is a brief introduction to Apache's htaccess file for web application deployment, distribution, or implementation on shared hosting environments.

The Apache htaccess file is not new; however it seems to only be used by more advanced Apache users and web application developers. This article aims to to point one on the right path to learn about htaccess and Apache directives by outlining how I have used and have seen Apache's htaccess file used in the real world..
