复制代码代码如下:function unescape($str){$ret = '';$len = strlen($str);for ($i = 0; $i {if ($str[$i] == '%' && $str[$i+1] == 'u'){$val = hexdec(substr($str, $i+2, 4));if ($val else if($val >6)).chr(0x80|($val&0x3f));else $ret .= chr(0xe0|($val>>12)).chr(0x80|(($val>>6)&0x3f)).chr(0x80|($val&0x3f));$i += 5;}else if ($str[$i] == '%'){$ret .= urldecode(substr($str, $i, 3));$i += 2;}else $ret .= $str[$i];}return $ret;}
