How can the issue of unchanged array indexes after using array_filter in PHP be resolved?

When using array_filter in PHP, the issue of unchanged array indexes can be resolved by using the array_values function to re-index the array after filtering. This function will re-order the array numerically starting from 0. 

// Original array
$originalArray = [0 => 'apple', 1 => 'banana', 2 => 'cherry'];

// Filtering the array
$filteredArray = array_filter($originalArray, function($value) {
    return $value != 'banana';
});

// Re-indexing the array
$reindexedArray = array_values($filteredArray);

// Output the re-indexed array
print_r($reindexedArray);
