composer require initphp/logger require_once "vendor/autoload.php"; use \InitPHP\Logger\Logger; use \InitPHP\Logger\FileLogger; $logFile = __DIR__ .

CREATE TABLE `logs` ( `level` ENUM('EMERGENCY','ALERT','CRITICAL','ERROR','WARNING','NOTICE','INFO','DEBUG') NOT NULL, `message` TEXT NOT NULL, `date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ) ENGINE = InnoDB CHARSET=utf8mb4 COLLATE utf8mb4_general_ci;require_once "vendor/autoload.php"; use \InitPHP\Logger\Logger; use \InitPHP\Logger\PDOLogger; use \InitPHP\Logger\FileLogger; $logFile = __DIR__ . '/logfile.log'; $table = 'logs'; $pdo = new \PDO('mysql:dbname=project;host=localhost', 'root', ''); $logger = new Logger(new FileLogger(['path' => $logFile]), new PDOLogger(['pdo' => $pdo, 'table' => $table]));public function emergency(string $msg, array $context = array()): void; public function alert(string $msg, array $context = array()): void; public function critical(string $msg, array $context = array()): void; public function error(string $msg, array $context = array()): void; public function warning(string $msg, array $context = array()): void; public function notice(string $msg, array $context = array()): void; public function info(string $msg, array $context = array()): void; public function debug(string $msg, array $context = array()): void; public function log(string $level, string $msg, array $context = array()): void;All of the above methods are used the same way, except for the log() method. You can use the log() method for your own custom error levels.
Example 1 :
$logger->emergency("Something went wrong");It prints an output like this to the log file.
2021-09-29T13:34:47+02:00 [EMERGENCY] Something went wrong Example 2:
$logger->error("User {username} caused an error.", ["username" => "john"]);It prints an output like this to the log file.
2021-09-29T13:34:47+02:00 [ERROR] User john caused an error. That is all.
