PHP implements encryption and decryption of Thunder links

The principle is very simple, it is base64 algorithm and string processing:

<?php
//迅雷链接普通链接转换工具
$url=$_GET[&#39;url&#39;];//获取链接
if($url[0]==&#39;t&#39;&&$url[7]==&#39;:&#39;)//链接为迅雷专用链 解密
{
$str1 = substr($url,10);
$tmp=base64_decode($str1);
$tmp=substr($tmp,2,-2);
echo $tmp;
}
else{//链接为普通链接 加密
$tmp=&#39;AA&#39;.$url.&#39;ZZ&#39;;
$tmp2=base64_encode($tmp);
$tmp3=&#39;thunder://&#39;.$tmp2;
echo $tmp3;}
?>

The above introduces how to implement encryption and decryption of Thunder links in PHP, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
