How can the array_column function in PHP be used to simplify the process of extracting values from an array based on specific keys?

The array_column function in PHP can be used to simplify the process of extracting values from an array based on specific keys by directly specifying the key you want to extract. This eliminates the need for loops or manual extraction methods, making the code cleaner and more efficient. 

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

// Extracting names using array_column
$names = array_column($data, 'name');

// Output the extracted names
print_r($names);
