Wa72SimpleLogger (collection of PHP logger classes)
Wa72SimpleLogger is a collection of very simple logger classes for PHP 5.4 implementing \Psr\Log\LoggerInterface (PSR-3),
the common logger interface standardized by the PHP Framework Interop Group (www.php-fig.org)., (*1)
Wa72SimpleLogger is intended for small projects or testing purposes if you don't need a full-featured logging solution
like Monolog., (*2)
If you just need to output a few log messages in a small PHP project but want to stick to the PSR-3 standard this package is for you. When your project grows you can simply replace it by a more advanced logging solution like Monolog., (*3)
Loggers
-
\Wa72\SimpleLogger\EchoLogger: Just echo the log message, (*4)
-
\Wa72\SimpleLogger\FileLogger: Log to a file, (*5)
-
\Wa72\SimpleLogger\ArrayLogger: Keep log messages in an array for later use (e.g. display it to the user), (*6)
-
\Wa72\SimpleLogger\ConsoleLogger: Log to the Symfony2 console => DEPRECATED: use Symfony\Component\Console\Logger\ConsoleLogger instead, (*7)
Installation
composer require wa72/simplelogger
Usage
$logger = new \Wa72\SimpleLogger\FileLogger('/path/to/logfile');
$logger->info('This is the first log message');
NEW: it's now possible to set a minimum log level in the constructor of FileLogger, EchoLogger and ArrayLogger:, (*8)
$logger = new \Wa72\SimpleLogger\FileLogger('/path/to/logfile', \Psr\Log\LogLevel::ERROR);
$logger->info('This is the first log message'); // this message will be discarded
$logger->error('This is an error message'); // this message will be logged
In one of my projects there was a "fetcher" class that fetched some information from a web service. It needed to log whether this fetch was successfull or not and how many data it fetched. It could be invoked either from the command line, by a background task, or by a user in the admin web page of the application. This was the use case for three logger classes:, (*9)
-
the fetcher class itself just logs to any PSR-3 compliant logger, (*10)
-
if called from a background task (cronjob), it is given a FileLogger, (*11)
-
if called from the command line, it is given a ConsoleLogger, (*12)
-
if called from the web interface, it is given an ArrayLogger. The output of this logger is then displayed to the user on the web page., (*13)
