Hi all, I want to check if these characters exist in a string by using preg_match:

^'£$%^&*()}{@'#~?><>,@|\-=-_+-¬'

Help please!

Answer 1

<?php  $string = 'foo';  if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string)) {     // one or more of the 'special characters' found in $string } 

Answer 2

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);
