How can a PHP developer exclude certain functionalities from conflicting with each other in a CMS like Joomla?

To exclude certain functionalities from conflicting with each other in a CMS like Joomla, PHP developers can use namespaces to encapsulate code and prevent naming collisions. By defining unique namespaces for different functionalities, developers can ensure that functions, classes, and variables do not conflict with each other.

// Define namespace for Functionality A
namespace FunctionalityA;

// Define namespace for Functionality B
namespace FunctionalityB;

// Example of using Functionality A
FunctionalityA\someFunction();

// Example of using Functionality B
FunctionalityB\someFunction();
