ciaos 人气:0想了解PHP实现的各类hash算法长度及性能测试实例的相关内容吗，ciaos在本文为您仔细讲解PHP hash算法长度及性能测试的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：PHP,hash,算法,长度,性能测试，下面大家一起来学习吧。
本文实例讲述了PHP实现的各类hash算法长度及性能测试。分享给大家供大家参考，具体如下：
Hash结果如下
<?php
$data = "hello world";
foreach (hash_algos() as $v) {
$r = hash($v, $data, false);
printf("%-12s %3d %s\n", $v, strlen($r), $r);
}
?>
运行结果：

性能测试如下：
<?php
define('testtime', 1000000);
$algos = hash_algos();
foreach($algos as $algo) {
$st = microtime();
for($i = 0; $i < testtime; $i++) {
hash($algo, microtime().$i);
}
$et = microtime();
list($ss, $si) = explode(' ', $st);
list($es, $ei) = explode(' ', $et);
$time[$algo] = $ei + $es - $si - $ss;
}
asort($time, SORT_NUMERIC);
print_r($time);
?>
运行结果：
