I'm having some trouble understanding how to utilize global classes or functions within a namespace in PHP. I have been working on a PHP project, and I want to organize my code using namespaces. However, I also have some global classes and functions that I would like to use within these namespaces.
For example, let's say I have a global class called `Database` and I want to use it inside a namespace called `MyNamespace`. How can I achieve this?
I have tried to simply use the class name within the namespace, like `MyNamespace\Database`, but it doesn't seem to work. I keep getting an error saying the class is not found.
Any help or guidance on how to make global classes and functions accessible within a namespace would be greatly appreciated. Thanks in advance!

Hey there! I understand your frustration, as I've also faced a similar issue before. To use global classes or functions within a namespace in PHP, you need to either import or fully qualify the namespaced class or function.
To import the global class or function, you can use the `use` keyword followed by the global class or function name, like this:
Then, within your namespace, you can use the imported class or function just by its name, like `Database`.
Alternatively, if you don't want to import the global class or function, you can fully qualify its name whenever you need to use it within the namespace. For example:
In this case, the backslash (`\`) before the class name denotes that it belongs to the global namespace.
I hope this clears up the confusion and helps you utilize global classes or functions within namespaces. Let me know if you have any more questions!
