How do you compare two arrays in PHP?

In PHP, you can use the array_diff function to compare the differences between two arrays. This function will return an array containing the elements that are different between the first array and the other arrays.

Here is an example:

$array1 = array("a", "b", "c", "d");
$array2 = array("b", "d", "e");

$diff = array_diff($array1, $array2);

print_r($diff);

The output result is:

Array
(
    [0] => a
    [2] => c
)

In the example above, array_diff($array1, $array2) compares two arrays, $array1 and $array2, and returns the elements that exist in $array1 but not in $array2.
