$a = somenumber;
$b = somenumber;

How do I know which variable has the biggest number? What is the shorter way for this task.

Each number is a positive integer without residue.

Thanks.

max returns the largest value from a list of values:

$biggest = max($a, $b);

If you care about which variable contains a higher value, use >, as other answers have said.

---

You can use ternary operator:

$big = ($a > $b) ? $a : $b;

---

Kidding?

if ($a > $b) {
    // $a is bigger
} else {
    // $b is bigger
}

or

$bigger = max($a, $b);

---

function is_a_bigger($a, $b) {
    return ($a - $b > 0);
}

---

if ($a > $b) {
 echo '$a is bigger';
} else 
 echo '$b is bigger';
}
