json が配列を変換すると中国語は NULL ソリューションになります

json が array
を変換するとき、中国語は NULL ソリューションになります $json='[{"ZtdID":"100000","ZtdNo":"001 ","ZtdName":"店舗番号 1 ","住所":"店舗番号 01, YY Road, ZZ District, XX都市 ","備考 ":"","エリアID":"01","ZtdTel":"0000-8888888","ZtdContact":"張三"},{"ZtdID":"100001","ZtdNo" :"002 ","ZtdName":"店舗No.1","住所":"XX市ZZ地区YY道路01号店","備考":"","エリアID":"01" ,"ZtdTel":"0000-8888888" ,"ZtdContact":"李三"}]';
var_dump(json_decode($json,true));

?>
出力は NULL
よく調べてみたところ、コーディングの問題でしたので解決していただけますか。

-----解決策---------
iconv('gbk',' UTF -8','私は中国人なので、json に変換したいと思っています');

PHP の json 中国語は gbk gb2312 形式をサポートしていません

$json='[{"ZtdID":"100000","ZtdNo":"001 ","ZtdName":"1号店 ","Address":"XX市ZZ区YY路01号铺 ","Remark":"","AreaID":"01","ZtdTel":"0000-8888888","ZtdContact":"张三"},{"ZtdID":"100001","ZtdNo":"002 ","ZtdName":"1号店 ","Address":"XX市ZZ区YY路01号铺 ","Remark":"","AreaID":"01","ZtdTel":"0000-8888888","ZtdContact":"李三"}]';<br />
debug( $json );<br />
debug( json_decode($json,true) );<br />

------------------出力は正常です
