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 know this is old, but I thought I'd share something I just found:

Use fmod and check for 0

$entityElementCount = (-($highScore-$totalKeywordCount))/0.29;
if (fmod($entityElementCount,1) !== 0.0) {
    echo 'Not a whole number!';
} else {
    echo 'A whole number!';
}

fmod is different from % because if you have a fraction, % doesn't seem to work for me (it returns 0...for example, echo 9.4 % 1; will output 0). With fmod, you'll get the fraction portion. For example:

echo fmod(9.4, 1);

Will output 0.4
