8,897 PointsWhat array_values($learn); did exactly?
Alena didn't demonstrate how "resetting" the array works after all. I tried running the code but they keys inside the array remain the same - with spaces in between the numbers (0, 3, 4, 5, 7).

11,975 PointsSorry, I misunderstood.
If a true "remove and shift" behavior is desired, the array can be reindexed using the array_values() function.
$array[9] = 'Pink';
$array[12] = 'Blue';
$array[5] = 'Red';
$array = array_values($array);
through this function you'll get this.
$array[0] = 'Pink';
$array[1] = 'Blue';
$array[2] = 'Red';
I hope this could help!

11,975 PointsHey Arikaturika,
array_values --> Outputs all values of an array. Do you want to reset the whole array or just single values? You can use unset for individual values. For example, to delete the second value you can do this.
unset ($learn[1]);
Best regards Phil

8,897 PointsHey, Philipp. I was actually talking about array_values, not unset. As far as I remember, Alena was saying that array_values resets the order of the keys inside an array?

1,106 PointsWhen you use the function it will reset the order of the indexes or 'refreshes' the array as Alena mentioned.
In the example above, unset will remove an element and its index from the array and leave a gap in the indexes. The array_values method will resolve the gap if that is what you need.

thanks!
