What potential pitfalls can occur when using namespaces in PHP, as seen in the provided code snippet?

Potential pitfalls when using namespaces in PHP include conflicts with existing class names or functions, confusion when referencing classes from different namespaces, and issues with autoloading classes. To avoid these pitfalls, it is important to carefully organize namespaces, use unique names, and ensure proper autoloading mechanisms are in place. 

<?php

namespace MyNamespace;

use AnotherNamespace\SomeClass;

// To fix potential conflicts, use fully qualified class names when importing classes
$object = new SomeClass();

// Alternatively, use an alias to refer to the imported class
use AnotherNamespace\SomeClass as AliasClass;
$object = new AliasClass();

// Ensure proper autoloading of classes by using a PSR-4 autoloader
spl_autoload_register(function ($class) {
    $file = __DIR__ . '/' . str_replace('\\', '/', $class) . '.php';
    if (file_exists($file)) {
        require_once $file;
    }
});

?>
