Are there any best practices for sorting arrays in PHP to avoid issues like comparing the word "Array"?

When sorting arrays in PHP, it's important to ensure that the elements being compared are of the same type. If the array contains a mix of strings and arrays, there may be issues with comparisons, such as accidentally comparing the word "Array" instead of the array contents. To avoid this, you can use the `usort` function with a custom comparison function that checks the type of the elements before comparing them.

// Example array with mixed elements
$array = [1, 'Array', 3, [4, 5]];

// Custom comparison function to handle different types
function customCompare($a, $b) {
    if (is_array($a) && is_array($b)) {
        return 0;
    } elseif (is_array($a)) {
        return 1;
    } elseif (is_array($b)) {
        return -1;
    } else {
        return ($a < $b) ? -1 : 1;
    }
}

// Sort the array using the custom comparison function
usort($array, 'customCompare');

// Output the sorted array
print_r($array);
