将字符串中中文字符编码后16进制字符小写： function urlencode_lower($str) { $outStr = ''; $len = strlen($str); for($i = 0; $i < $len; $i++) { if(ord($str{$i}) > 127) { $ch = substr($str, $i, 2); $p = 1; $outStr .= strtolower(urlencode($ch)); } else { $ch = substr($str, $i, 1); $p = 0; $outStr .= urlencode($ch); } $i += $p; } return $outStr; } echo urlencode_lower('妈妈咪'); //%c2%e8%c2%e8%df%e4
