How can one handle empty arrays when attempting to extract specific content from a webpage using PHP?

When attempting to extract specific content from a webpage using PHP, it's important to handle empty arrays to prevent errors. One way to handle this is by checking if the array is empty before trying to access its elements. This can be done using the `empty()` function in PHP.

// Check if the array is not empty before trying to access its elements
if (!empty($array)) {
    // Access the elements of the array here
    foreach ($array as $item) {
        // Process each item as needed
    }
} else {
    // Handle the case where the array is empty
    echo "The array is empty";
}
