Straight to point i have 3 tables like following -
QTY Types Table
-------------------- | ID | QTY types | | 1 | 1 | | 2 | 2-4 | | 3 | 5-9 | | 4 | 10-24 | | 5 | 25+ | --------------------
Poster Size Table
----------------------- | ID | Poster Size | +-----+---------------+ | 1 | A4 | | 2 | A3 | | 3 | A2 | | 4 | A1 | | 5 | A0 | -----------------------
Price table (based on Qty ID- column title)
-------------------------------------------------------------------------------- | qty_id_1 | qty_id_2 | qty_id_3 | qty_id_4 | qty_id_5 | poster_size | +-----------+------------+------------+------------+------------+--------------+ | 4 | 3.5 | 2.75 | 3.25 | 3 | 1 | | 6 | 5.5 | 4 | 4.75 | 4.5 | 2 | | 12 | 9.5 | 6.5 | 8.5 | 8 | 3 | | 18 | 16 | 10.5 | 14 | 12.5 | 4 | | 34 | 33 | 25 | 31 | 28 | 5 | --------------------------------------------------------------------------------
I just wanted to Generate Price According to User Input for example if user selects Qty.id=2 Poster_size.id=3
so answer will be $9.5 .
All of this data are static so after that i just wanted to generate JSON file using fwrite (php)
something like this
{ "qty_1":{ "poster_size_1":[ { "price":4 } ], "poster_size_2":[ { "price":6 } ], "poster_size_3":[ { "price":12 } ], "poster_size_4":[ { "price":18 } ], "poster_size_5":[ { "price":34 } ] }, "qty_2":{ "poster_size_1":[ { "price":3.5 } ], "poster_size_2":[ { "price":5.5 } ], "poster_size_3":[ { "price":9.5 } ], "poster_size_4":[ { "price":16 } ], "poster_size_5":[ { "price":33 } ] } }
By this i can easily access obj.qty_1.poster_size_3.price
as $9.5 .
How can i populate JSON file like this or is there any alternate way to populate different JSON structure to get my required data. (im new to JSON objects)
Help Appreciated | Thanks in Advance
explain like this a array like json.
$arr = array(
'qty_1' => array(
"poster_size_1" => array(
"price" => 4
),
'qty_2' => array(
'key' => 'value',
'key2' => array(
value, value2
)
)
);
this array will make
{"qty_1": {"poster_size_1" : {"price": 4}}} blabla...
创建您想要json的数组/对象,并使用json_encode()
函数将数组转换为json,然后写入文件。
