How can PHP be used to determine if a value is a multiple of X?

To determine if a value is a multiple of X in PHP, you can use the modulo operator (%). The modulo operator returns the remainder of a division operation. If the remainder is 0, then the value is a multiple of X. Here is a PHP code snippet that checks if a given value is a multiple of X: 

$value = 15;
$X = 3;

if ($value % $X == 0) {
    echo "$value is a multiple of $X.";
} else {
    echo "$value is not a multiple of $X.";
}
