Problem

You want to perform regular expression with PHP.

Solution

Again PHP implementation of regular expression is very similar to Perl.

In the simpliest form, pattern matching:

$ php -q<<EOT
<?php

$str="hello world";
if(ereg("world","$str")) {
echo("got a match");
}

?>
EOT

got a match

Example

Similarly eregi operates the same, just it is case insensitive.

$ php -q<<EOT
<?php

$str="hello world";
if(eregi("WORLD","$str")) {
echo("got a matchn");
}

?>
EOT

got a match
