All responses in this thread have been very nice; but you could also try 
a much simpler 2-step check:

1. is_numeric
2. if true > check if there's a decimal character in the string:

if(is_numeric($str) && false === strpos('.', $str)) {
    // it's an int for sure
} else {
    // might be a number, but it's definitly not an int
}
