PHP配列回転json,文字列中国語乱符号解決(unicode)

$arr_tem = array(
    array(
        "id"=> 1,
        "name"=>"  ",
        "OilMass"=>"",
        "YeweiVol"=>"",
        "children"=>array("")
    )
);

 

   json

 

$json_arr = json_encode($arr_tem);
 {"id":1,"name":"\u6cb9\u5e93","OilMass":"","YeweiVol":"","children":
\u6cb9\u5e93  unicode  
function decodeUnicode($str)
{
    return preg_replace_callback('/\\\\u([0-9a-f]{4})/i',
        create_function(
            '$matches',
            'return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");'
        ),
        $str);
}
$jsonstr = decodeUnicode(json_encode($arr_tem));

 
 

 
 
 
PHP5.4以上のバージョンでは、このように解決できます.
すなわちJsonはUnicodeを符号化する.
 

$json_arr = json_encode($arr_tem,JSON_UNESCAPED_UNICODE);
