<para>
PHP also supports regular expressions using a Perl-compatible syntax
using the <link linkend="book.pcre">PCRE functions</link>. Those functions
support non-greedy matching, assertions, conditional subpatterns, and a
number of other features not supported by the POSIX-extended regular
expression syntax.
</para>
</tip>
<warning>
<para>
These regular expression functions are not binary-safe. The <link
linkend="book.pcre">PCRE functions</link> are.
</para>
</warning>
<para>
Regular expressions are used for complex string manipulation.
PHP uses the POSIX extended regular expressions as defined by POSIX
1003.2. For a full description of POSIX regular expressions see the <link xlink:href="&url.regex.man;">regex
man pages</link> 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
<command>man /usr/local/src/regex/regex.7</command> in order to read it.
