What are the best practices for handling empty arrays in PHP to avoid warnings?

When working with empty arrays in PHP, it's important to check if the array is empty before trying to access its elements to avoid warnings. One common practice is to use the `empty()` function to check if the array is empty before performing any operations on it. 

// Check if the array is empty before accessing its elements
if (!empty($myArray)) {
    // Perform operations on the array
    foreach ($myArray as $element) {
        // Do something with each element
    }
} else {
    // Handle the case when the array is empty
    echo "The array is empty.";
}
