The best placed to go if you dont understand a meaning of something is to head over to wikipedia! Anyway PCRE stands for [b]P[/b]erl [b]C[/b]ompatible [b]R[/b]egular [b]E[/b]xpressions

Here is an [a href=\"http://en.wikipedia.org/wiki/PCRE\" target=\"_blank\"]an explanation too[/a]

Also I swer php.net mentions what PCRE stands for. yeah I thought so, [a href=\"http://uk2.php.net/manual/en/ref.pcre.php\" target=\"_blank\"]php.net explains it here[/a]

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]I know the RE means but PC it's a no, no to me. :)[/quote]
What?

PC stands for Perl Compatible.

Perl is another programming language, with extensive support for Regular Expressions.

just to let you know, the other famous regular expression "type" is called POSIX (google tells me that this stands for: Portable Operating System Interface for X).

POSIX is less powerful than PCRE but POSIX modern is an extended version of the traditional POSIX but it's still considered less feature rich than POSIX.

if you've used 'grep' in a Linux/UNIX terminal, you've probably used a POSIX style regexp.
