[SOLVED] Using The Gettype In If Conditions

[phpSensei]

I need to know the correct way of doing something like this:

 

<?php

if(gettype($_POST['value']) != "int"){
die("Needs To Be an Interger");
}
else
{
echo "..."; // Too Lazy To Come up with something;
}

?>

For Post variables I think they are always interpreted as strings, But what a better idea in this case might be is to use a regex to see if its a number within your given value range.

Thanks, I got to the idea before I read your post lol..

 

You Helped anyways.

You can also do something like this, if not dealing with POST vars

 

<?php

// show a function which only accepts ints

public function myFunction(int $i) {
    //code
}

public function myFunction2(array $b) {
    foreach ($b as $a) {
     //etc etc etc 
   }
}
?>
