Are there any specific considerations to keep in mind when sorting arrays with mixed data types in PHP?

When sorting arrays with mixed data types in PHP, it's important to remember that PHP's sorting functions may not always behave as expected due to the different data types present in the array. To address this issue, you can use the `usort()` function along with a custom comparison function that takes into account the data types of the elements being compared. 

// Example array with mixed data types
$array = [10, "2", 5, "apple", "orange", true, false];

// Custom comparison function to sort mixed data types
function customSort($a, $b) {
    if (gettype($a) == gettype($b)) {
        return $a < $b ? -1 : 1;
    } else {
        return gettype($a) < gettype($b) ? -1 : 1;
    }
}

// Sorting the array using usort with custom comparison function
usort($array, 'customSort');

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