------ Solution --------------------

$ Json = '[{"ZtdID": "100000", "ZtdNo": "001", "ZtdName": "Shop 1", "Address ": "Shop No. 01, YY Road, ZZ district, XX city", "Remark": "", "AreaID": "01", "ZtdTel": "0000-8888888 ", "ZtdContact": "Zhangsan" },{ "ZtdID": "100001", "ZtdNo": "002", "ZtdName": "Shop 1", "Address ": "Shop No. 01, YY Road, ZZ district, XX city", "Remark": "", "AreaID": "01", "ZtdTel": "0000-8888888 ", "ZtdContact": "Li San"}] ';
Debug ($ json );
Debug (json_decode ($ json, true ));

------------------ The output is normal.
