How can namespaces be used to specify which Exception class to use in PHP?

When working with multiple libraries or frameworks in PHP, there may be situations where different Exception classes have the same name. To specify which Exception class to use, namespaces can be used to differentiate between them. By specifying the full namespace of the Exception class when catching or throwing an exception, PHP will know exactly which class to use. 

<?php

use MyNamespace\Exception\CustomException;

try {
    // Some code that may throw an exception
    throw new CustomException("An error occurred.");
} catch (CustomException $e) {
    echo "Caught CustomException: " . $e->getMessage();
} catch (Exception $e) {
    echo "Caught generic Exception: " . $e->getMessage();
}
