What is the best way to delete specific elements from an array in PHP without affecting the index sequence?

When deleting specific elements from an array in PHP without affecting the index sequence, one approach is to use the `unset()` function to remove the elements and then reindex the array using `array_values()` to reset the keys. 

// Sample array
$array = [1, 2, 3, 4, 5];

// Elements to delete
$elementsToDelete = [2, 4];

// Delete specific elements without affecting index sequence
foreach ($elementsToDelete as $element) {
    $key = array_search($element, $array);
    if ($key !== false) {
        unset($array[$key]);
    }
}

// Reindex the array
$array = array_values($array);

// Output the modified array
print_r($array);
