PHP把unicode编码的json字符串转中文

一条js的json数据:

    $s = '[{"param_name":"email","param_caption":"\u90ae\u7bb1","operator":"\u5305\u542b","value":"aaaa\u5927\u592b\u6492"}]';

方法一:

json_encode($log['result_data'],JSON_UNESCAPED_UNICODE);

方法二:

 /**
     * 把unicode编码的字符串转为人眼可看的字符串
     * @param $unicode_str
     *
     * @return string
     */
    function unicodeDecode($unicode_str){
        $unicode_str = str_replace('"', '\"', $unicode_str);
        $unicode_str = str_replace("'", "\'", $unicode_str);
        $json = '{"str":"'.$unicode_str.'"}';
 
        $arr = json_decode($json,true);
 
        if(empty($arr)){
            return '';
        }
 
        return $arr['str'];
    }

返回:

[{"param_name":"email","param_caption":"邮箱","operator":"包含","value":"aaaa大夫撒"}]
