<?php

$numbers = [];

for ($i = 1; $i < 10000; $i++) {
    $numbers[] = random_int(1, 10000);
}

$start = microtime(true);
foreach ($numbers as $number) {
    $test = sprintf("%x",$number);
}

echo microtime(true) - $start . PHP_EOL;

$start = microtime(true);
foreach ($numbers as $number) {
    $test = dechex($number);
}

echo microtime(true) - $start . PHP_EOL;
