php url传递url

url 可以base64_encode 后再传值，接受页面再 decode 

<?php
//http://local.test.com/?a=1&url=http://www.baidu.com?b=2&c=3
var_dump($_GET);
/*array (size=3)
  'a' => string '1' (length=1)
  'url' => string 'http://www.baidu.com?b=2' (length=24)
  'c' => string '3' (length=1)
  */



$url=base64_encode('http://www.baidu.com?b=2&c=3');

echo "<a href='index.php?a=1&url=".$url."'>test</a>";

var_dump(base64_decode($_GET['url']));
