How can namespaces be effectively utilized to prevent variable name conflicts in PHP frameworks?

To prevent variable name conflicts in PHP frameworks, namespaces can be effectively utilized. By defining namespaces for different classes, functions, and variables, we can encapsulate them within a specific namespace scope, reducing the chances of naming conflicts with other parts of the codebase.

namespace MyFramework;

class MyClass {
    public function myMethod() {
        // Code here
    }
}
