[^a-zA-Z0-9\u4e00-\u9fa5\s]我用这个匹配符号，php 中preg_replace总是报错，怎么破？
[^a-zA-Z0-9\u4e00-\u9fa5\s] 求大神赐教
------解决方案--------------------
header('Content-type: text/html;charset=utf-8');<br />$s = 'asa-de+中文123';<br />$p = '/[^a-zA-Z0-9\x{4e00}-\x{9fa5}\s]/u';<br /><br />echo preg_replace($p, '', $s); //asade中文123<br /><br />echo preg_replace('/[^\w\s]/u', '', $s); //asade中文123<br />------解决方案--------------------
当目前为止，php 的正则还不支持 \u4e00 这样的表述
所以你没有错，错在 php
