use Psr\Log\LoggerInterface; class MyClass { private $logger; public function __construct(LoggerInterface $logger) { $this->logger = $logger; } public function doStuff() { // do something that might produce an error try { // do something } catch (\Exception $e) { $this->logger->error('An error occurred', [ 'exception' => $e, ]); } } }In this example, we have a class that is using the LoggerInterface error to log errors. The class takes an instance of a logger as a constructor argument and uses it to log an error message when an exception is thrown. The use of the Psr\Log package library is apparent in the code where the LoggerInterface is imported using the `use` statement. We can then use the `error` method of the logger object to log errors, and pass the error message and additional details as arguments. Overall, the LoggerInterface error is a great way to include logging functionality in your PHP applications. Its use provides consistent logging across various applications.
