How can differences between two arrays be identified in PHP?

To identify differences between two arrays in PHP, you can use the array_diff() function. This function compares the values of two arrays and returns the differences as a new array. The values that are present in the first array but not in the second array are returned. 

$array1 = [1, 2, 3, 4, 5];
$array2 = [2, 3, 4, 6, 7];

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

print_r($differences);
