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
