Useful mod_rewrite Resources

May 26, 2008 |

There are many free and useful mod_rewrite resources online.

Regex Tools
If you’re going to spend more than just a little time messing with regexes, you’re eventually
going to want a tool that helps you visualize what’s going on. There are a number of
them available, each of which has different strengths and weaknesses. You’ll find that
most of the really good tools for regular expression development come out of the Perl community, where regular expressions are particularly popular and tend to get used in
almost every program.

Regex Coach, which is available for Windows and Linux, and can be downloaded from http://www.weitz.de/regex-coach/. Like Rebug, Regex Coach allows you to step through a regular expression and watch what it does and does not match. This can be extremely instructive as you learn to write your own regular expressions.

Reference Sources
Because mod_rewrite is built on top of the Perl Compatible Regular Expression (PCRE) vocabulary, it is god to take a look at the Perl regular expression documentation, which you can find online at http://perldoc.perl.org/perlre.html or by typing perldoc perlre at your command line, and the PCRE documentation, which you can find online at http://pcre.org/pcre.txt.
