最近在处理网站的图片，电话号码加密，今天在网上也看到了一个“url地址参数加密函数”，特收来供学习php的朋友们参考！
url地址参数加密
function keyED($txt,$encrypt_key)
{
$encrypt_key = md5($encrypt_key);
$ctr=0;
$tmp = "";
for($i=0;$i<strlen($txt);$i++)
{
if ($ctr==strlen($encrypt_key))
$ctr=0;
$tmp.= substr($txt,$i,1) ^ substr($encrypt_key,$ctr,1);
$ctr++;
}
return $tmp;
}
function encrypt($txt,$key)
{
$encrypt_key = md5(mt_rand(0,100));
$ctr=0;
$tmp = "";
for ($i=0;$i<strlen($txt);$i++)
{
if ($ctr==strlen($encrypt_key))
$ctr=0;
$tmp.=substr($encrypt_key,$ctr,1) . (substr($txt,$i,1) ^ substr($encrypt_key,$ctr,1));
$ctr++;
}
return keyED($tmp,$key);
}
function decrypt($txt,$key)
{
$txt = keyED($txt,$key);
$tmp = "";
for($i=0;$i<strlen($txt);$i++)
{
$md5 = substr($txt,$i,1);
$i++;
$tmp.= (substr($txt,$i,1) ^ $md5);
}
return $tmp;
}
function encrypt_url($url,$key)
{
return rawurlencode(base64_encode(encrypt($url,$key)));
}
function decrypt_url($url,$key)
{
return decrypt(base64_decode(rawurldecode($url)),$key);
}
function geturl($str,$key)
{
$str = decrypt_url($str,$key);
$url_array = explode('&',$str);
if (is_array($url_array))
{
foreach ($url_array as $var)
{
$var_array = explode("=",$var);
$vars[$var_array[0]]=$var_array[1];
}
}
return $vars;
}
函数描述及例子
希望这个url参数加密函数对大家有所帮助
$key = 'key';
//生产加密参数地址
for ($i=0;$i<10;$i++)
{
echo "<a href=./deurl.php?url=".encrypt_url("id=$i&sdf=asdf&time=".time(),$key).">文章$i</a><br>";
}
//获取参数地址
$get = geturl($_GET['url'],$key);
var_dump($get);
