EddieJaoude\Zf2Logger

Zend Framework 2 Event Logger.

• Log incoming Requests & Response data with host name
• Manually log your application information with priorities (i.e. emerg..debug)
• Change your logging output via config without changing code
• Multiple logging outputs (i.e. file(s), stdout, stderr etc)
• Filter errors to log per environment (i.e production > error, development > debug)
• Default log information includes (Session Id, Host, IP)

Installation via Composer

Steps

1. Add to composer.

    "require" : {
        "eddiejaoude/zf2-logger" : "0.*"
    }

Update your dependencies php composer.phar update eddiejaoude/zf2-logger

2. Copy the configuration file config/module.config.php.dist to config/autoload/zf2Logger.global.php

3. Add module to application config (/config/application.config.php)

   //...
   'modules' => array(
        'EddieJaoude\Zf2Logger',
   ),
   //...

Then you are good to go. Logging READY! All requests & responses will be logged automatically as DEBUG

Example usage of manual logging & prority

As the Zend\Log\Logger is returned from the Service call, one can use the methods:

• emerg // Emergency: system is unusable
• alert // Alert: action must be taken immediately
• crit // Critical: critical conditions
• err // Error: error conditions
• warn // Warning: warning conditions
• notice // Notice: normal but significant condition
• info // Informational: informational messages
• debug // Debug: debug messages

    //...
    $serviceLocator->get('EddieJaoude\Zf2Logger')->emerg('Emergency message');
    //...

Use an alias for decoupling

Instead of using EddieJaoude\Zf2Logger in your code, put an Alias in your service manager, therefore allowing you to swap out different logger libraries later on without modifying your code & usage.

i.e.

    //...
    'aliases'    => array(
        // alias used, so can be swapped out later without changing any code
        'Logger' => 'EddieJaoude\Zf2Logger'
    ),
    //...

Then your usage in your code becomes...

    //...
    $serviceLocator->get('Logger')->emerg('Emergency message');
    //...

Add to default logging parameters

Additional default logging information includes:

• IP
• Host
• Session Id

To log more additional default information, use $logger->addCustomExtra($extraArray). Full example below.

1. Change the alias to your new service (point 2 below) i.e.

    'aliases' => array(
        // ...
        'Logger' => 'Zf2Logger',
        // ...
    ),

1. Create your new service

    // ...
    'Zf2Logger' => function($sm) {
        $logger = $sm->get('EddieJaoude\Zf2Logger');
        $logger->addCustomExtra(
            array(
                'host' => !empty($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : 'CLI',
            )
        );

        return $logger;
    },
    // ...

Example - built in logging

Each output includes & is prepended with the host - this is especially useful when working with multi layer/tier architecture, i.e. F/E (UI) -> B/E (API). As these can all write to the same output in the stack execution order or alternatively to different outputs.
