Attempted to load class "Memcached" from the global namespace. Did you forget a "use" statement?

The error message you're encountering indicates that PHP is trying to load a class named "Memcached" from the global namespace, but it can't find the class definition. This error typically occurs when you're trying to use a class without properly including its namespace or including the required PHP extension.

To resolve this issue, follow these steps:

1. Check if "Memcached" Extension is Installed:
   The error could occur if you're trying to use the "Memcached" class without having the Memcached extension installed and enabled in your PHP configuration. Make sure you have the "Memcached" extension installed and enabled by checking your PHP configuration or installing it if necessary.

2. Use the Correct Namespace:
   If you're using a PHP library that defines the "Memcached" class in a specific namespace, you need to ensure that you're using the correct namespace in your code. You can either use the full namespace or import it with a use statement.

   For example, if the "Memcached" class is defined in the "MyNamespace" namespace:

   phpCopy code
   use MyNamespace\Memcached;
   
   

3. Autoloading or Including the Class:
   Make sure that you're properly including or autoloading the class definition in your code. If you're not using a framework that provides autoloading, you need to use the require or include statement to include the class file before using it.

   phpCopy code
   require_once 'path/to/Memcached.php'; // Adjust the path accordingly
   
   

4. Check for Typos:
   Make sure you've spelled "Memcached" correctly and that the case matches the actual class name. PHP is case-sensitive.

5. Check for Global Namespace Usage:
   If you're not using a namespace for the "Memcached" class, you might be trying to use it directly from the global namespace. In that case, ensure that the class is properly included or defined.

By addressing these points, you should be able to resolve the "Attempted to load class 'Memcached' from the global namespace" error in your PHP code. If you're working within a specific framework or library, consult its documentation for specific instructions on how to use the "Memcached" class.
