how to create dynamic menu in php mysql?

To create a dynamic menu in PHP and MySQL, you can use the following steps:

Create a MySQL database table to store the menu items. The table should have columns for the menu item ID, menu item name, menu item URL, and parent menu item ID (if the menu item is a sub-menu item).

Insert the menu items into the MySQL table. Each menu item should have a unique ID and a name, URL, and parent ID (if applicable).

Query the MySQL table to retrieve the menu items. You can use a SELECT statement to retrieve the menu items and use the parent_id column to create a hierarchical structure for the menu.

Loop through the menu items and generate the HTML code for the menu. You can use PHP code to generate the HTML code for the menu and create a nested list structure to represent the hierarchical structure of the menu.

Here’s an example code snippet that demonstrates how to create a dynamic menu in PHP and MySQL:

// Connect to the MySQL database
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Query the MySQL database to retrieve the menu items
$result = $mysqli->query('SELECT * FROM menu_items ORDER BY parent_id, name');

// Create a nested list structure to represent the hierarchical structure of the menu
echo '
';
$parent_id = 0;
while ($row = $result->fetch_assoc()) {
    if ($row['parent_id'] != $parent_id) {
        if ($parent_id != 0) {
            echo '
';
        }
        $parent_id = $row['parent_id'];
        echo '
' . $row['name'] . '
';
    } else {
        echo '
' . $row['name'] . '
';
    }
}
echo '
';
echo '';

In the above code, replace username, password, database, and menu_items with your own values. The script will query the MySQL database to retrieve the menu items and generate a nested list structure to represent the hierarchical structure of the menu. Each top-level menu item will be enclosed in a

tag, and each sub-menu item will be enclosed in a nested
tag.
