Hi Chris,

You need to return true or false from "return_int" function.
As "0" will be treated as false it will not be returned to filtered
result array.

Change the function "return_int" like below, then you should be able
to get proper array.

function return_int($value){
      if(ctype_digit($value)){
             echo $value."\t";
              return true;
      }else{
            return false;
     }
}

Thanks,
Sanjay Mantoor
