Logger

This is a simple Logger implementation that other Loggers can inherit from. It simply delegates all log-level-specific methods to the log method to reduce boilerplate code that a simple Logger that does the same thing with messages regardless of the error level has to implement.

Logger Instance

Simple Logger Implementation.

$logger = new \Samy\Psr3\Logger();

Logger Interface

Describes Logger interface.

emergency

System is unusable.

$logger->emergency($message, $context);

alert

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

$logger->alert($message, $context);

critical

Critical conditions. Example: Application component unavailable, unexpected exception.

$logger->critical($message, $context);

error

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

$logger->error($message, $context);

warning

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

$logger->warning($message, $context);

notice

Normal but significant events.

$logger->notice($message, $context);

info

Interesting events. Example: User logs in, SQL logs.

$logger->info($message, $context);

debug

Detailed debug information.

$logger->debug($message, $context);

log

Logs with an arbitrary level.

$logger->log($level, $message, $context);
