I have written following regular expression /^[A-Za-z0-9-_\s]*$/ in PHP which allows numbers, letters, spaces, hyphen and underscore. I want to display those matches which are not valid against the regex i.e “My Name is Blahblah!!!” should give me “!!!” output.
Use the caret symbol inside the character class to invert the match and remove the start (
^) and end ($) characters:http://php-regex.blogspot.com/2008/01/how-to-negate-character-class.html
