Hello everyone,

 I'm trying to determine if an argument is alphanumeric. Is there a
function to do this?

 I thought PHP had a IS_ALPHA_NUMERIC function, but I can't seem to find
 it anywhere. Was it wishful thinking ? Please help.

 If you do know of this function, then please send me the syntax.
  is_alpha_numeric($string) is not working.

 If you do know of another way to this, then please send me that as well.
 My expected string has the form 'A200A'. Both, letters and numbers, will
 change depending on the item. The value will ve passed via a hidden form.

 Thanks in advance.
