The function presented by Emin isn't IMO simple, simpler is:

Código PHP:

  <?php 
if (!function_exists('is_md5')) { 
  function is_md5($var) { 
   return preg_match('/^[A-Fa-f0-9]{32}$/',$var); 
  } 
} 
?>   

Morover (as I proved somewhere else) it's faster 'cuz preg_match() is faster then ereg()
