Exceptions logging extension for YII2

Installation

The preferred way to install this extension is through composer.

Run

php composer.phar require pozitronik/yii2-exceptionslogger "dev-master"

or add

"pozitronik/yii2-exceptionslogger": "dev-master"

to the require section of your composer.json file.

Requirements

Yii2, PHP >= 8.0

Configuration

Run a included migration:

yii migrate/up --migrationPath=vendor/pozitronik/yii2-exceptionslogger/migrations

It creates the sys_exceptions table, which will store exceptions data.

Usage

Direct logger

This extension provides the SysExceptions::log() function, that can accept any Throwable interface as its first parameter. The exception data will be saved in sys_exceptions table (in case of failure, the data will be written into runtime/exception.log file).

Example:

try {
	$i = $i/0;
} catch (Throwable $t) {
	SysExceptions::log($t);//just silently log exception
	SysExceptions::log(new RuntimeException("Someone tried divide to zero"), false, true);//silently log own exception and mark it as known error
	SysExceptions::log(new RuntimeException("It prohibited by mathematics"), true);//log own exception and throw it
}

Default exceptions handler

You can use the pozitronik\sys_exceptions\models\ErrorHandler class as default application error handler to log all exceptions automatically. Define it in your application config, like:

$config = [
    'components' => [
        'errorHandler' => [
            'class' => pozitronik\sys_exceptions\models\ErrorHandler::class,
            'errorAction' => 'site/error'
        ]
    ];

How to add custom data to a log record?

It is possible to add custom string data (e.g. some trace identifier) to every logged error. Configure the customDataHandler parameter for the SysExceptionsModule module:

$config = [
        'modules' => [
            'SysExceptionsModule' => [
                'params' => [
                    'customDataHandler' => static function():string {
                        return Yii::$app->request?->csrfToken;//for example
                    }
                ]
            ],
        ]
    ]

The data will be stored in the custom_data text field.
