Laravel - How to save an Array to Database

Question

I have an array like this :

array:4 [▼
  "*name1*" => 1
  "*name2*" => 1
  "*name3*" => 2
  "*name4*" => 1
]

And I have an table Item with 'id'; 'name'; 'time' 'id'; 'name'; 'time'

Then how to I can save this array into Item Table using Laravel ?

I already do this but I know it's not working. But I don't know how to save it

foreach ($data_participant[$i]['attributes']['stats']['itemGrants'] as $key => $value) {
      $itemGrants = new ItemGrant;
      $itemGrants->item = $key;
      $itemGrants->time = $value;

      $itemGrants->save();
}

Just simply use json_encode function to convert from array to JSON string. You may refer to this link for further information.

For example, convert your array to JSON string format:

$array = ["name"=>1,"name2"=>2,"name3"=>3];
$json_array = json_encode($array);

Now, the output will be a JSON string:

[{"name":"1"},{"name2":"2"},{"name":"3"}];

You can save it to a database as a string in JSON format.

If you want the data back in an array, then you have to decode. For example:

$string_json = "[{"name":"1"},{"name2":"2"},{"name":"3"}]";    
$array_output = json_decode($string_json,true);

Note the true boolean parameter passed to json_decode , this is important as without it json_decode will return an array of stdObject rather than an associative array.

Now, you can get back the array as your input.
