复制代码 代码如下:

<?php

$str = 'test';

$cm = md5($str);

$bm = md5($str, true);

$cstr = implode(unpack('H*', $bm));

$bstr = pack('H*', $cm);

echo 'str:'. $str . "<br >n";

echo 'cm :' . $cm . "<br >n";

echo 'cstr:' . $cstr . "<br >n";

echo 'urlencode(bm) :' . urlencode($bm) . "<br >n";

echo 'urlencode(bstr):' . urlencode($bstr) . "<br >n";
