What potential complications can arise when handling multiple modules belonging to the same module group in PHP?

When handling multiple modules belonging to the same module group in PHP, potential complications can arise due to naming conflicts or duplicated functionality. To solve this issue, it is important to namespace the modules to avoid conflicts and ensure each module has a unique identifier within the group. 

```php
<?php

// Define namespaces for each module within the module group
namespace ModuleGroup\Module1;
// Module 1 code here

namespace ModuleGroup\Module2;
// Module 2 code here

// Usage example
use ModuleGroup\Module1;
use ModuleGroup\Module2;

// Access Module 1 functionality
Module1\someFunction();

// Access Module 2 functionality
Module2\someFunction();

?>
