How can namespaces be utilized in PHP to improve class loading and organization?

Namespaces in PHP can be utilized to improve class loading and organization by grouping classes together under a common namespace, which helps avoid naming conflicts and organizes classes into a logical hierarchy. By using namespaces, you can autoload classes more efficiently and clearly define the relationships between classes.

// Define a namespace for a group of classes
namespace MyNamespace;

class MyClass {
    // Class implementation
}

// Using the class from the defined namespace
$obj = new MyNamespace\MyClass();
