What are some best practices for handling the return value of arsort in PHP?

When using the `arsort` function in PHP to sort an array in descending order, it's important to remember that the function modifies the original array in place and returns a boolean value indicating success or failure. To handle the return value, you can simply check if `arsort` was successful before proceeding with further operations on the sorted array. 

$myArray = ['b' => 2, 'a' => 1, 'c' => 3];
if (arsort($myArray)) {
    // Sorting successful, proceed with further operations
    foreach ($myArray as $key => $value) {
        echo "$key: $value\n";
    }
} else {
    // Sorting failed
    echo "Failed to sort array";
}
