[Function] Check if number is a multiple
This function, given a number, multiple, will tell you if it can be divided evenly into it.
PHP Code:
function is_multiple($number, $multiple) {
$num = $number / $multiple;
$res = strstr($num, '.');
if ($res == false) {
$return = true;
} else {
$return = false;
}
return $return;
}
//USAGE:
echo is_multiple(25, 5);
//Will print: [I]true[/I]
echo is_multiple(6, 5);
//Will print: [I]false[/I]
Re: [Function] Check if number is a multiple
I think that can be shortened to something like this:
PHP Code:
function is_multiple($number, $multiple)
{
return ($number % $multiple) == 0;
}
