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

I always use typecasting to check if variables contain a whole number, handy when you don't know the origin or type of the value.

if ((string) $var === (string) (int) $var) {
    echo 'whole number';
} else {
    echo 'whatever it is, it\'s something else';
}

In your particular case, I would use is_int()

if (is_int($var) {
    echo 'integer';
}
