As I understand, you're trying to check if the passed value is an
integer or not and then check it's value right?
Use the TYPECASTING technique.
example:
$var = (int) $var;
In this case you're converting ur $var to integer before processing it.
Typecasting is a very well known technique in any programming language.
The alternative is to check the type of ur $var. That is using
is_int($var) if it holds then compare.
However the best way is to limit the user on the client side to enter
the right datatype like a JS validator to see if the user entered the
right type of info & then an slight type checking on the server side
to make ur life easier.
Hope this was useful.
