    Hi
    I know that below code checks for a NULL value but I also need to ensure that the value is not an integer or null value.How to check this?

    Code:

    if($Id == NULL || )

if(strlen($id)>0 && !is_int($id))
{
   // $id is not null, and it's not an int
}
    Code (markup):
    that should do it
