php各类hash算法长度及性能

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);
}
?>

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);
?>
