Are there any best practices for integrating new listings into a list on a website using PHP?

When integrating new listings into a list on a website using PHP, it is important to ensure that the new listing is added to the existing list without causing any conflicts or errors. One way to achieve this is by using an array to store the list of listings and then adding the new listing to the array. This allows for easy manipulation and display of the list.

// Example code snippet to integrate new listings into a list using PHP

// Sample array of existing listings
$listings = array("Listing 1", "Listing 2", "Listing 3");

// New listing to be added
$new_listing = "New Listing";

// Add the new listing to the existing list
$listings[] = $new_listing;

// Display the updated list
foreach ($listings as $listing) {
    echo $listing . "<br>";
}
