[PHP] is_numeric

[pete M]

not a php expert but have filed this bug report re validating 
is_numeric('3e0');
http://bugs.php.net/bug.php?id=32943

Now tried
  function isnumeric($n) {
   if (ereg("^[0-9]{1,50}.?[0-9]{0,50}$", $n)) {
     return true;
   } else {
     return false;
   }
  }
and that doent seem to work either..
any ideas.. need to validate anything without 0-9 and a dot within
tia
