Zend 3 - using logger as service - php

Question

I am quite novice with ZF3 and I can't figure out how should I define a logger module as a service and how could I use (reuse) it in other modules. The official documentation is poor from this point of view. Any short example would be good.

Answer 1

If you want to use zend-log in ZF app, after installation you need to do 2 thing:
To register Zend\Log in the application config under the 'modules' key.
Add config for your logger in global.php or module config
'log' => [
'MyLogger' => [
'writers' => [
'stream' => [
'name' => 'stream',
'priority' => \Zend\Log\Logger::ALERT,
'options' => [
'stream' => '/tmp/php_errors.log',
'formatter' => [
'name' => \Zend\Log\Formatter\Simple::class,
'options' => [
'format' => '%timestamp% %priorityName% (%priority%): %message% %extra%',
'dateTimeFormat' => 'c',
],
],
'filters' => [
'priority' => [
'name' => 'priority',
'options' => [
'operator' => '<=',
'priority' => \Zend\Log\Logger::INFO,
],
],
],
],
],
],
],
],
after that just take it from Service Manager and use it:
$logger = $container->get('MyLogger'); // <-- the key that you register in config above
$logger->info('Logging info message in the file');
You probably want to take logger from SM and than inject it in a class that you want to use it.
There is a god blog post about Logging with zend-log
