What are the implications of using the greater/less than operators with arrays in PHP?

When using the greater/less than operators with arrays in PHP, PHP will compare the arrays based on their length and not the actual values within the arrays. To compare arrays based on their values, you can use the array_diff() function to compare the values of the arrays. 

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

if (empty(array_diff($array1, $array2)) && empty(array_diff($array2, $array1))) {
    echo "Arrays are equal";
} else {
    echo "Arrays are not equal";
}
