How can developers ensure proper variable scope and avoid conflicts when using global variables in PHP?

To ensure proper variable scope and avoid conflicts when using global variables in PHP, developers should use namespaces to encapsulate their global variables. By defining global variables within a namespace, developers can prevent naming conflicts with variables defined elsewhere in the codebase. 

namespace MyNamespace;

$globalVariable = "Hello, world!";
