如何将数组值插入到 Laravel PHP 中的数组中

Question

The data column of user table is as follows.

data                 | {"user": [["id", true], ["name", true], ["email", true], ["address", true], ["dob", true]], "prime_user": [["id", true], ["name", true], ["email", true], ["address", true], ["dob", true]], "premium_user": [["id", true], ["name", true], ["email", true], ["address", true], ["dob", true]]}

Now for this data, I want to add another value ["first_name", true] next to the id, to each array(user, prime_user, premium_user) of these data. ie I want to update the above value as below

{
   "user":[
      [
         "id",
         true
      ],
      [
         "first_name",
         true
      ],
      [
         "name",
         true
      ],
      [
         "email",
         true
      ],
      [
         "address",
         true
      ],
      [
         "dob",
         true
      ]
   ],
   "prime_user":[
      [
         "id",
         true
      ],
      [
         "first_name",
         true
      ],
      [
         "name",
         true
      ],
      [
         "email",
         true
      ],
      [
         "address",
         true
      ],
      [
         "dob",
         true
      ]
   ],
   "premium_user":[
      [
         "id",
         true
      ],
      [
         "first_name",
         true
      ],
      [
         "name",
         true
      ],
      [
         "email",
         true
      ],
      [
         "address",
         true
      ],
      [
         "dob",
         true
      ]
   ]
}

I have tried something like this, but it is not working. Can anyone help me out? Thanks.

$data = $user->data;
$inserted = array("first_name", true);
foreach ($data as $d) {
    array_splice($d, 1, 0, $inserted );
}
$user->data = $data;
$user->save();

Answer 1

array_splice uses the reference but you are using $d which is a local variable for the loop and it doesn't affect the $data variable.

try using array_splice($data[$key], ... ) instead, add $key in loop like this: foreach($data as $key => $d)

Answer 2

Change your loop like this and you will get your result

 foreach($data as $key => $value)
    {
        $data[$key] = array_merge(array_slice($value, 0, 1),[$inserted ],array_slice($value, 1));
    }

may it helps....
