将数组转换为Json以保存到数据库

Question

Hello i have an array like this:

$data = Array(
[0] => {"detail":"l,red","sku":"#123","price":"50","stok":""}
[1] => {"detail":"l,black","sku":"#123","price":"50","stok":""}
[2] => {"detail":"m,red","sku":"#123","price":"50","stok":""}
[3] => {"detail":"m,black","sku":"#123","price":"50","stok":""}
[4] => {"detail":"s,red","sku":"#123","price":"50","stok":""}
[5] => {"detail":"s,black","sku":"#123","price":"50","stok":""}
)

when i use this :

$data = json_encode($data , JSON_FORCE_OBJECT);

but the result like :

{"0":"{\"detail\":\"l,red\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}","1":"{\"detail\":\"l,black\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}","2":"{\"detail\":\"m,red\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}","3":"{\"detail\":\"m,black\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}","4":"{\"detail\":\"s,red\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}","5":"{\"detail\":\"s,black\",\"sku\":\"#123\",\"price\":\"50\",\"stok\":\"\"}"}

i don't like "\\" result. is there something wrong?

If you don't like these slashes, you should decode inner JSON strings first:

$data = json_encode(array_map(function ($item) {
    return json_decode($item, true);
}, $data), JSON_FORCE_OBJECT);
