How can a loop be implemented to iterate through multiple arrays when using array_diff() in PHP?

When using array_diff() in PHP to compare multiple arrays, you can implement a loop to iterate through each array and find the differences. This can be achieved by using a foreach loop to iterate through each array and comparing it with the first array using array_diff(). By looping through all arrays and finding the differences with the first array, you can effectively compare multiple arrays.

<?php
// Arrays to compare
$array1 = [1, 2, 3, 4];
$array2 = [2, 3, 4, 5];
$array3 = [3, 4, 5, 6];

// Initialize the result array with the first array
$result = $array1;

// Loop through each array and find the differences
foreach([$array2, $array3] as $array) {
    $result = array_diff($result, $array);
}

// Output the differences
print_r($result);
?>
