php类似于javascript encodeURI和decodeURI解码的方法

<script language="javascript"> var a = encodeURI("电影"); alert(a); var b = decodeURI(a); alert(b) </script>

<?php $a = urlencode(iconv("gb2312", "UTF-8", "电影")); //等同于javascript encodeURI("电影"); echo $a; $b = iconv("utf-8","gb2312",urldecode("%E7%94%B5%E5%BD%B1")); //等同于javascript decodeURI("%E7%94%B5%E5%BD%B1"); echo $b; ?>

如果编码是UTF-8的话就可以直接用urlencode 或 urldecode 转换
