Regular expressions are used for complex string manipulation in PHP. The functions that support regular expressions are:

• ereg()

• ereg_replace()

• eregi()

• eregi_replace()

• split()

• spliti()

These functions all take a regular expression string as their first argument. 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 man /usr/local/src/regex/regex.7 in order to read it.

To enable regexp support configure PHP --with-regex[=TYPE]. TYPE can be one of system, apache, php. The default is to use php.

Пример 1. Regular Expression Examples <?php // Returns true if "abc" is found anywhere in $string. ereg("abc", $string);             // Returns true if "abc" is found at the beginning of $string. ereg("^abc", $string); // Returns true if "abc" is found at the end of $string. ereg("abc$", $string); // Returns true if client browser is Netscape 2, 3 or MSIE 3. eregi("(ozilla.[23]|MSIE.3)", $HTTP_USER_AGENT);   // Places three space separated words into $regs[1], $regs[2] and $regs[3]. ereg("([[:alnum:]]+) ([[:alnum:]]+) ([[:alnum:]]+)", $string, $regs); // Put a <br /> tag at the beginning of $string. $string = ereg_replace("^", "<br />", $string); // Put a <br /> tag at the end of $string. $string = ereg_replace("$", "<br />", $string); // Get rid of any newline characters in $string. $string = ereg_replace("\n", "", $string); ?>

For regular expressions in Perl-compatible syntax have a look at the PCRE functions. The simpler shell style wildcard pattern matching is provided by fnmatch().
