Hmm, I'm surprised but it is faster...

<?php

define('ITERATIONS', 10000000);

$x = 'hello';

$a = microtime(true);
for ($i = 0; $i < ITERATIONS; $i++) {
if ($x == 'a' || $x == 'b' || $x == 'c') {
}
}
$b = microtime(true);
var_dump($b - $a);

$a = microtime(true);
for ($i = 0; $i < ITERATIONS; $i++) {
if (in_array($x, ['a', 'b', 'c'])) {
}
}
$b = microtime(true);
var_dump($b - $a);
