How can PHP code snippets from online sources be effectively integrated into custom forum functionalities without causing conflicts?

When integrating PHP code snippets from online sources into custom forum functionalities, conflicts can arise due to naming collisions, incompatible code structures, or duplicate function definitions. To prevent conflicts, it is essential to carefully review the code snippet, ensure it aligns with the existing codebase, and make necessary adjustments to avoid conflicts. Additionally, using namespaces, unique function names, and proper error handling can help mitigate potential conflicts.

// Example of integrating a PHP code snippet into custom forum functionalities

// Ensure the code snippet does not conflict with existing functions or classes
if (!function_exists('new_custom_function')) {
    function new_custom_function() {
        // Code from online source goes here
    }
}

// Call the new custom function within the forum functionality
new_custom_function();
