Question

How can I remove certain items of an array?

Let’s say I have an array with 10 elements, I want to remove elements at index 0, 3, and 8.

Answer 1

unset() supports removing individual array elements. The order of the remaining elements isn’t affected.

unset($array[0], $array[3], $array[8]);

To reindex the array, simply call array_values() on it. Order is still maintained until you call a sorting function on it; this just reindexes:

$array = array_values($array);
