php regular expressions No ending delimiter ‘^’ found in

The code is as follows:

if(preg_match($exp, $value)){
   return "";           
}

• the value of $exp is: ^[0-9]*$
• the value of $value is: 7

and the output gives :

Warning: preg_match() [function.preg-match]: No ending delimiter ‘^’ found in /…

Answer 1

$exp should be something like /^[0-9]*$/ for it to work the way you intended. It is assuming ^ is your regex delimiter, because it is the first character – you’d want your first char to be something else. See preg_match manual entry for details.
