怎样用PHP加密URL的实现方法　php开源.ma

   自学编程网和大家一起来看看PHP中URL加密的实现方法，我们用一个实例向大家说明加密是具体实现，下面一起来看代码：php开源.ma

<?php

function base64_en($str){
 $str = base64_encode($str);
 $str .= randStr(5);
 $str = base64_encode($str);
 $str = randStr(3).$str;
 return $str;
}
function randStr($len){
 $str = "ABCDEFGHIJKLMNOPQRSTUVWSYZabcdefghijklmnopqrstuvwsyz0123456789";
 return substr(str_shuffle($str),0,$len);
}
echo $s1 = base64_en("");//加密后的串

function base64_de($str){
 $len = strlen($str);
 $str = substr($str,3,$len-2);
 $str = base64_decode($str);
 $str = substr($str,0,$len-5);
 $str = base64_decode($str);
 return $str;
}
echo "\n";
echo base64_de($s1);//解密后的串
