How to Dynamically Generate and Display Website Navigation Menus Using PHP Arrays

In web development, the navigation menu is an essential component. To efficiently and flexibly manage navigation menus, we can use PHP arrays to dynamically generate and display them. This article will explain how to achieve this with PHP arrays, accompanied by practical code examples.

1. Create a Navigation Menu Array

First, we need to define an array containing the navigation menu items. Each menu item should have two properties: the menu name and its corresponding link. Here is a simple PHP array example:

$navigationMenu = array(
    array("name" => "Home", "link" => "index.php"),
    array("name" => "About Us", "link" => "about.php"),
    array("name" => "Products", "link" => "products.php"),
    array("name" => "Contact Us", "link" => "contact.php")
);
    

In the above example, we've defined an array containing four menu items, each with a name and link.

2. Dynamically Generate the Navigation Menu

Next, we can use a PHP loop to traverse the array and dynamically generate the HTML navigation menu. Here's the PHP code for this task:

echo "<ul>";
foreach ($navigationMenu as $menu) {
    echo "<li><a href='" . $menu['link'] . "'>" . $menu['name'] . "</a></li>";
}
echo "</ul>";
    

In this example, we use a `foreach` loop to iterate through each item in the array. For each menu item, we use the `echo` statement to output the corresponding HTML tags. Finally, we wrap the navigation items in `ul` and `li` tags to generate an ordered list.

3. Display the Navigation Menu on the Website

To display the generated navigation menu on the website, we need to insert the code at the appropriate location in the HTML structure. Below is an example of how to display the dynamic navigation menu:

<div class="navigation-menu">
    <?php
    echo "<ul>";
    foreach ($navigationMenu as $menu) {
        echo "<li><a href='" . $menu['link'] . "'>" . $menu['name'] . "</a></li>";
    }
    echo "</ul>";
    ?>
</div>
    

In this example, we embed the PHP code for generating the navigation menu inside a `
