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.

|
|
<warning>
|
|
<para>
|
|
These regular expression functions are not binary-safe. The <link
|
|
linkend="book.pcre">PCRE functions</link> are.

As of PHP 5.3.0 this extension is deprecated, calling any function

provided by this extension will issue an <constant>E_DEPRECATED</constant>
|

notice.

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.
