_____________________________________________________________
<script>
window.location.href="bb.php?lr=<?=base64_encode(这是任意字符串);?>";
</script>
-------------------------------------------------------------
bb.php代码:
_____________________________________________________________
$lr=isset($_GET['lr'])&&!empty($_GET['lr'])?$_GET['lr']:null;
echo base64_decode($lr);
-------------------------------------------------------------

Answer 2

。
base64不行的，里面有+,=
可以用urlencode

urlencode就行了在bb.php 用$_GET["lr"]或者直接$lr;
