Unfortunately, applications using [Zend Framework 2](https://github.com/zendframework/zf2) cannot provide their existing `Zend\Log\Logger` loggers, as they don't comply with [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md). In fact, the two interfaces are not compatible, as they declare some common methods with different signatures. For example: [Zend alert](https://github.com/zendframework/zendframework/blob/release-2.1.0/library/Zend/Log/LoggerInterface.php#L28) vs. [Psr alert](https://github.com/php-fig/log/blob/504b915845b0fe47819fcbabbfbea18e95f5cf5c/Psr/Log/LoggerInterface.php#L41). This library serves as a backwards-compatible replacement for `Zend\Log\Logger` instances that provides a [Psr\\Log](https://github.com/php-fig/log)-compliant interface to the underlying `Zend\Log\Logger` instance. The result is that you can provide either logger depending on the interface required by a given context, while still having all messages go through `Zend\Log\Logger` and benefiting from its robustness. Installation ------------ [](#installation) The only supported method of installation is [Composer](https://getcomposer.org/). `composer require "michaelmoussa/zend-psr-log"` Configuration ------------- [](#configuration) To begin, you must add the `ZendPsrLog` module to your `application.config.php` module list as with any ZF2 application. ``` return [ 'modules' => [ ..., 'ZendPsrLog', ... ], ... ]; ``` Further configuration depends on how you are presently getting your instances of a `Zend\Log\Logger`. ### "I define a `log` entry in my configuration with `Zend\Log\Logger` as the key, and then let `Zend\Log\LoggerAbstractServiceFactory` do the work." [](#i-define-a-log-entry-in-my-configuration-with-zendloglogger-as-the-key-and-then-let-zendlogloggerabstractservicefactory-do-the-work) Then you're done! `ZendPsrLog` adds its own factory for creating `Zend\Log\Logger` instances, which will be invoked before the Abstract Factory. ### "I define a `log` entry in my configuration with a different key, then let `Zend\Log\LoggerAbstractServiceFactory` do the work." [](#i-define-a-log-entry-in-my-configuration-with-a-different-key-then-let-zendlogloggerabstractservicefactory-do-the-work) For each key you use, you'll need to add a `'My\Key\Here' => new \ZendPsrLog\LoggerFactory('My\Key\Here')` entry to your service manager config. ### "I define a log key in my configuration with no key, and then have my own `'Zend\Log\Logger' => '...'` factory definition in the service manager config" [](#i-define-a-log-key-in-my-configuration-with-no-key-and-then-have-my-own-zendloglogger---factory-definition-in-the-service-manager-config) You need to replace your `'Zend\Log\Logger' => '...'` entry with `'Zend\Log\Logger' => new \ZendPsrLog\LoggerFactory(null)`, as your definition will override the one done by the `ZendPsrLog\LoggerFactory`. If your custom factory is doing some special logic, you will have to extend `ZendPsrLog\LoggerFactory` on your own to ensure it persists. ### "I use `new \Zend\Log\Logger(...)`." [](#i-use-new-zendloglogger) 1. Please don't. :) You should be using the `ServiceManager`. 2. Replace `new \Zend\Log\Logger` with `new \ZendPsrLog\Logger`. Usage ----- [](#usage) ### As a `Zend\Log\LoggerInterface` [](#as-a-zendlogloggerinterface) The `ZendPsrLog\Logger` is an extension of `Zend\Log\Logger`, so any class you have in your application that is presently using a `Zend\Log\Logger` can use the `ZendPsrLog\Logger` without any additional configuration. ### As a `Psr\Log\LoggerInterface` [](#as-a-psrlogloggerinterface) Suppose you have a class that requires a `Psr\Log\LoggerInterface` instance: ``` use Psr\Log\LoggerInterface; class Foo { public function __construct(LoggerInterface $logger) { ... } } ``` And you obtain an instance of the `ZendPsrLog\Logger`: ``` /** @var \ZendPsrLog\Logger $logger */ $logger = $serviceManager->get('Zend\Log\Logger'); ``` Just use the `->getPsrLogger()` method to obtain a `Psr\Log\LoggerInterface` to your existing `Zend\Log\Logger`: ``` $foo = new Foo($logger->getPsrLogger()); ``` ### Health Score 32 — LowBetter than 72% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity23 Limited adoption so far Community10 Small or concentrated contributor base Maturity61 Established project with proven stability Bus Factor1 Top contributor holds 96.2% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
