What are the potential challenges or limitations of using pre-built PHP platforms for online seminars?

One potential challenge of using pre-built PHP platforms for online seminars is limited customization options. To address this limitation, developers can create their own custom modules or plugins to extend the functionality of the platform.

// Example of creating a custom module in a pre-built PHP platform
// Define a new custom module
class CustomModule {
    public function __construct() {
        // Constructor code
    }

    public function customFunction() {
        // Custom functionality code
    }
}

// Instantiate the custom module
$customModule = new CustomModule();

// Call the custom function
$customModule->customFunction();
