);
I'm using this code to do it, but it doesn't work :(

Answer
Solution:
When you want to clear the complete array, why not usingunset($data)?
Your code does not work they way as you expect it, because in your loop you are defining a new variable$item. You are then unsetting this variable$item which has no effect on original the values of your$data array.
If you want to use a loop you need to define it like that:
foreach ($data as $index => $item) {
unset($data[$index]);
}
This clears all values from$data but not unsetting the$data array itself.
A more efficient way compared to the loop would be to just assign a empty array to$data like:
$data = [];
