In terms of scalability and performance, what are some best practices for handling tab navigation in a PHP project with multiple users and classes?

To handle tab navigation in a PHP project with multiple users and classes, it is best to use a modular approach by creating separate classes for each tab and dynamically loading the content based on the user's selection. This approach helps in keeping the codebase organized, scalable, and maintainable.

<?php

// Tab class example
class Tab {
    private $content;

    public function __construct($content) {
        $this->content = $content;
    }

    public function getContent() {
        return $this->content;
    }
}

// Usage example
$tabs = [
    'tab1' => new Tab('Tab 1 Content'),
    'tab2' => new Tab('Tab 2 Content'),
    'tab3' => new Tab('Tab 3 Content'),
];

// Get selected tab content
$selectedTab = isset($_GET['tab']) ? $_GET['tab'] : 'tab1';
echo $tabs[$selectedTab]->getContent();

?>
