try { // some code that may throw an exception } catch (\Exception $e) { \Logger::err($e->getMessage()); }
if (!file_exists($file)) { \Logger::err("File not found: $file"); }This code snippet shows how the `Logger` class is used to log an error message when a file is not found. In this case, the `file_exists()` function returns false, indicating that the file is not present in the specified location. The `err()` function of the `Logger` class is then called to log an error message. Both of these examples suggest that the `Logger` class is part of some PHP logging library, such as Monolog or Log4php. These libraries provide robust logging features that can be easily integrated into PHP applications to log errors, warnings, and other types of messages.
