php - How get efficiently the array which is contained in a string?

Question

I'm on laravel. In my controller, i get an array stored in a hidden field. The array comes into a string

'[1,2]'

How i can get the php array from this string? And the array items must be the intenger value.

[1,2]

Of course, have in mind various ways to achieve this, but i want the best. Thanks!

I think the easiest way in this case would be json_decode():

$string = '[1,2]';
$array = json_decode($string, true);

var_dump($array);

// Output:
array(2) {
  [0] =>
  int(1)
  [1] =>
  int(2)
}

Use explode() or json_decode() functions

But the "[" and the "]" stay included. For example: "[ 1 , 2 , 3 ]" $newArray = explode (',', $arr); $newArray is [ [1 , 2 , 3] ]
