PHP check if variable is a whole number

Question

I have this PHP code:

$entityElementCount = (-($highScore-$totalKeywordCount))/0.29;

What i want to know is, how to check whether $

Answer 1

A simple solution for positive whole numbers only. This may not work for everything.

$string = '0x539';
$ceil = ceil($string);

if($ceil < 1){
  $ceil = FALSE; // or whatever you want i.e 0 or 1
}

echo $ceil; // 1337

You can use floor() instead of ceil() if so desired.
