Form validation

Hi!

I want to find out if a string contains specified characters.
Which function should i use?

Thanks for your answer!

if you only need to find a string use strpos(), otherwise i say using preg_match or ereg.

like

$string = "radley";
$match = preg_match("/[ary]/i");

$match would now conatain TRUE

oops, made a mistake,

$match = preg_match("/[ary]/i");

should be

$match = preg_match("/[ary]/i", $string);
