json值如何转换成数组？或者取得里面的值

Question

1由于php里的$_POST不能获取json值，所以用file_get_contents("php://input")方法获取。2获取后，得到值：title=ww&imgFile=%2Fpublic%2Fupload%2Fimage%2F20180712%2F20180712024544_27715.jpg3我想在值里获取imgFile=%2Fpublic%2Fupload%2Fimage%2F20180712%2F20180712024544_27715.jpg里的值4PHP版本是5.5如何获得？

Answer 1

用explode方法来处理字符串
explode('&''title=ww&imgFile=%2Fpublic%2Fupload%2Fimage%2F20180712%2F20180712024544_27715.jpg');
