How can the use of namespaces in PHP help to prevent conflicts when including files with class definitions?
When including files with class definitions in PHP, conflicts can arise if two classes with the same name are included. This can lead to fatal errors and unexpected behavior in the code. Using namespaces in PHP helps to prevent these conflicts by providing a way to organize classes into separate, unique namespaces.
// File: MyClass.php
namespace MyNamespace;
class MyClass {
// class definition
}
```
```php
// File: AnotherClass.php
namespace AnotherNamespace;
class MyClass {
// class definition
}
```
```php
// File: main.php
require 'MyClass.php';
require 'AnotherClass.php';
$myClass = new MyNamespace\MyClass(); // Instantiate MyClass from MyNamespace
$anotherClass = new AnotherNamespace\MyClass(); // Instantiate MyClass from AnotherNamespace
