Are class declarations in PHP always global, or are there exceptions?

In PHP, class declarations are typically global, meaning they can be accessed from anywhere within the script. However, you can use namespaces to encapsulate classes and avoid naming conflicts with other classes. By defining classes within a namespace, you can limit their scope and prevent them from being accessed outside of that namespace. 

namespace MyNamespace;

class MyClass {
    // class implementation
}
