      PHP also supports regular expressions using a Perl-compatible syntax
      using the <A
HREF="ref.pcre.html"
>PCRE functions</A
>. Those functions
      support non-greedy matching, assertions, conditional subpatterns, and a
      number of other features not supported by the POSIX-extended regular
      expression syntax.

     PHP uses the POSIX extended regular expressions as defined by POSIX
     1003.2. For a full description of POSIX regular expressions see the regex
     man pages included in the regex directory in the PHP distribution. It's
     in manpage format, so you'll want to do something along the lines of
     <B
CLASS="command"
>man /usr/local/src/regex/regex.7</B
> in order to read it.
