PHP regular expressions: No ending delimiter '^' found in

Question

I\'ve been having some trouble with regular expressions.

This is my code

$pattern = \"^([0-9]+)$\";

if (preg_match($pattern, $input))
   echo \"yes         


        

Answer 1

You can use T-Regx library, that doesn't need delimiters

pattern('^([0-9]+)$')->match($input);
