How can error handling be improved in PHP when dealing with empty arrays?

When dealing with empty arrays in PHP, it is important to check if the array is empty before trying to access its elements to avoid errors like "Undefined offset" or "Invalid argument supplied for foreach()". One way to improve error handling is to use functions like empty() or isset() to check if the array is empty before performing any operations on it.

// Check if the array is empty before trying to access its elements
if (!empty($array)) {
    foreach ($array as $element) {
        // Perform operations on each element of the array
    }
} else {
    // Handle the case when the array is empty
}
