MaplePHP - PSR-3 Logger

PHP PSR-3 Logger library – your reliable companion for efficient logging in PHP applications. This library adheres to the PSR-3 standard, providing a seamless and standardized approach to logging messages across different components of your application.

Log-levels

1. emergency: System is unusable
2. alert: Action must be taken immediately
3. critical: Critical conditions
4. error: Runtime errors that do not require immediate action but usually logged and monitored.
5. warning: Exceptional occurrences that are not errors.
6. notice: Normal but significant events.
7. info: Interesting events (User logs in, SQL logs.)
8. debug: Detailed debug information.
9. log: Logs with an arbitrary level.

Stream/file handler

Add namespaces

use MaplePHP\Log\Logger;
use MaplePHP\Log\Handlers\StreamHandler;

Create simple stream logger

$log = new Logger(new StreamHandler("/path/to/logger.log"));
$log->warning("The user {firstname} has been added.", ["firstname" => "John", "lastname" => "Doe"]);

Rotatable log files

Create simple stream rotatables loggers. Will create a new log file if size is more than MAX_SIZE (5000 KB) and remove log files if total file count is more than MAX_COUNT 10.

$log = new Logger(new StreamHandler("/path/to/logger.log", StreamHandler::MAX_SIZE, StreamHandler::MAX_COUNT));
$log->warning("The user {firstname} has been added.", ["firstname" => "John", "lastname" => "Doe"]);

Database handler

Add namespaces

use MaplePHP\Log\Logger;
use MaplePHP\Log\Handlers\DBHandler;

1. Connect to the database.

2. Create database table

Execute bellow once to create the database table. Then remove the script again!

$dbHandler = new DBHandler();
$error = $dbHandler->create();
if (count($error) > 0) {
    echo "<pre>";
    print_r($error);
    echo "</pre>";
} else {
    echo "<p>The Logger database table has been installed!</p>";
}

3. Write to database log

$log = new Logger(new DBHandler());
$log->warning("The user {firstname} has been added.", ["user_id" => 4, "firstname" => "Daniel"]);

PHP error log handler (error_log())

You can (not required) specify a log file location in ErrorLogHandler. If argument is empty, then server default location.

Add namespaces

use MaplePHP\Log\Logger;
use MaplePHP\Log\Handlers\ErrorLogHandler;

$log = new Logger(new ErrorLogHandler("/path/to/logger.log"));
$log->warning("The user {firstname} has been added.", ["firstname" => "John", "lastname" => "Doe", "data" => ["city" => "Stockholm", "coor" => "122,1212"]]);
