What is the purpose of comparing two arrays in PHP?

Comparing two arrays in PHP allows you to check if they have the same values in the same order. This can be useful when you need to verify the integrity of data or ensure that two sets of data match. By comparing arrays, you can easily identify any discrepancies or differences between them. 

$array1 = [1, 2, 3, 4];
$array2 = [1, 2, 3, 4];

if ($array1 == $array2) {
    echo "The arrays are equal.";
} else {
    echo "The arrays are not equal.";
}
