解决PHP中json_encode函数处理中文乱码的问题 两种方法

$code = json_encode($str); return preg_replace("#\\\u(([0-9a-f]+?){4})#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $code);

或者使用

$new_arr = array();foreach($arr as $key=>$val){ $new_arr[$key] = urlencode($val);}print_r($new_arr);echo $json_arr = urldecode(json_encode($new_arr));
