Do I need to extract integers

Question

Is there any point in avoiding the integer in the request after converting it using intval() ?

I use an integer like this:

 $sql .= " LIMIT " . $this->db->escape(intval($offset)) . ", 10"; 

Answer 1

No, intval will always return an integer ( 0 on failure).

Answer 2

Not. because as a result of intval you cannot get anything but a number.
