How can the PHP functions array_filter() and array_search() be effectively used together to achieve a specific goal, like modifying data based on IDs?

To modify data based on IDs using array_filter() and array_search() in PHP, you can first use array_search() to find the key of the specific ID in the array. Then, you can use array_filter() to modify the data based on that key. 

// Sample data array
$data = [
    ['id' => 1, 'name' => 'John'],
    ['id' => 2, 'name' => 'Jane'],
    ['id' => 3, 'name' => 'Alice']
];

// Find the key of the specific ID
$key = array_search(2, array_column($data, 'id'));

// Modify data based on the key
$data[$key]['name'] = 'Updated Name';

print_r($data);
