Match not having .php using regular expressions

Question

With regular expressions, how do I match anything not having:

.php

exactly? I tried:

^[^\.php]+$

But this seems to be match not . or p or h or p.

... which is not like in the example. That works: $filter = ".php$"; $text = "stuff.php3"; if (preg_match("/^(?:(?!" . $filter . ").)*$/i", $text)) { echo "yeahhh"; } — fabien, Mar 25 '14 at 06:28

Use negative lookahead in your regex to check whether there is any .php is available or not.

$text = 'some php text';
if(preg_match("/^(?!.*\.php)(.*)$/", $text, $m)){
    print_r($m[1]);
}

^ is the beginning of the string.

(?!.*\.php) is checking if there is no .php in upfront.

And (.*)$ is capturing everything till the end.
