How can the code be optimized to prevent empty arrays in PHP?

To prevent empty arrays in PHP, you can add a check to ensure that the array is not empty before performing any operations on it. This can be done using the `empty()` function or by checking the array's length using `count()`. By adding this simple check, you can avoid errors that may occur when trying to access or manipulate an empty array. 

// Example code with optimization to prevent empty arrays
$array = []; // Empty array

if (!empty($array)) {
    // Perform operations on the array
    foreach ($array as $item) {
        // Do something with each item
    }
} else {
    echo "Array is empty, cannot perform operations.";
}
