本文为大家讲解的是php的md5 16位二进制与32位字符串相互转换示例,感兴趣的同学参考下. 密码很多时候都会用 md5保存,并且很多时候都是16位二进制格式的md5,php 里面 md5($str, true) 可以很方便的获取。更多时候md5结果是一组32个字符组成的字符串,其实转换很简单 <?php $str = 'test'; $cm = md5($str); $bm = md5($str, true); $cstr = implode(unpack('H*', $bm)); $bstr = pack('H*', $cm); echo 'str:'. $str .

<?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";
