php中将json字符串转为数组或对象的方法
方法一：
$json= '[{"id":"1","name":"\u5f20\u96ea\u6885","age":"27","subject":"\u8ba1\u7b97\u673a\u79d1\u5b66\u4e0e\u6280\u672f"},{"id":"2","name":"\u5f20\u6c9b\u9716","age":"21","subject":"\u8f6f\u4ef6\u5de5\u7a0b"}]';
$students= json_decode($json);//得到的是 object
foreach($studentsas $obj){
echo "姓名：".$obj->name." 年 龄：".$obj->age." 专 业：".$obj->subject."
";}

echo "姓名：".$students[$i]['name']." 年 龄：".$students[$i]['age']." 专 业：".$students[$i]['subject']."
