What are the best practices for manipulating arrays in PHP to ensure consistent counting after deletion?

When deleting elements from an array in PHP, it's important to reindex the array to ensure consistent counting. This can be achieved by using the array_values() function, which reindexes the array starting from index 0. By reindexing the array after deletion, you can avoid any gaps in the array keys and ensure that counting remains consistent.

// Example of deleting an element from an array and reindexing to ensure consistent counting
$array = [1, 2, 3, 4, 5];

// Delete element at index 2
unset($array[2]);

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

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