Abstract Logger Class

Abstract logger class, providing common functionality. A formatter interface is available as well as an adapter one. Adapters can be created easily using the built in AdapterFactory. A LoggerFactory is also available that allows developers to create new instances of the Logger or load them from config files (see Phalcon\Config\Config object).

  • LoggerInterface

Phalcon Logger.

A logger, with various adapters and formatters. A formatter interface is available as well as an adapter one. Adapters can be created easily using the built-in AdapterFactory. A LoggerFactory is also available that allows developers to create new instances of the Logger or load them from config files (see Phalcon\Config\Config object).

Methods

public function alert( string $message, array $context = [] ): void;

Action must be taken immediately.

Example: Entire website down, database unavailable, etc. This should trigger the SMS alerts and wake you up.

public function critical( string $message, array $context = [] ): void;

Critical conditions.

Example: Application component unavailable, unexpected exception.

public function debug( string $message, array $context = [] ): void;

Detailed debug information.

public function emergency( string $message, array $context = [] ): void;

System is unusable.

public function error( string $message, array $context = [] ): void;

Runtime errors that do not require immediate action but should typically be logged and monitored.

public function info( string $message, array $context = [] ): void;

Interesting events.

Example: User logs in, SQL logs.

public function log( mixed $level, string $message, array $context = [] ): void;

Logs with an arbitrary level.

public function notice( string $message, array $context = [] ): void;

Normal but significant events.

public function warning( string $message, array $context = [] ): void;

Exceptional occurrences that are not errors.

Example: Use of deprecated APIs, poor use of an API, undesirable things that are not necessarily wrong.
