protected function _initLogger() {
$writer = new Zend_Log_Writer_Stream('/var/log/YOUR_WEBSITE/output.log');
$format = '%timestamp% %priorityName%: %message%' . PHP_EOL;
$formatter = new Zend_Log_Formatter_Simple($format);

Zend_Registry::set('logger', $logger);
}Functions starting with _init will automatically be run during the bootstrap. This will setup the logger to log to a file in your logs directory, with a slightly clearer format than the default one (inc. simplified date format). It then saves the logger instance in the Zend_Registry, which means we can access it from our controllers!
Now in your Controller:
Now in your Controller:
class IndexController extends Zend_Controller_Action {
private $logger;
public function init() {$this->logger = Zend_Registry::get('logger');}
public function indexAction() {$this->logger->info("Hello");}
}Next, lets setup our logger to log the details of all requests, as this is really useful for debugging. We do this with a Controller Plugin, by implementing the preDispatch function (create application/plugins/Logger.php):
class Application_Plugin_Logger extends Zend_Controller_Plugin_Abstract {
public function preDispatch(Zend_Controller_Request_Abstract $request) {
$uri = $_SERVER['REQUEST_URI'];
if ($uri != "/favicon.ico") {
$logger = Zend_Registry::get('logger');
$logger->info("* REQUESTED URI ".$_SERVER['REQUEST_URI']
.", CONTROLLER ".$request->getControllerName()
.", ACTION ".$request->getActionName());
}
}
}
Note: we don't bother logging browsers requests for favicon.ico, as they are not very interestingThen we need to register the plugin, which we do back in our bootstrap, at the end of _initLogger():
$front = Zend_Controller_Front::getInstance(); $front->registerPlugin(new Application_Plugin_Logger());
Finally, we setup the ErrorController to log all error information by adding this code to errorAction():
$logger = Zend_Registry::get('logger');
$params = $errors->request->getParams();
$paramsString = "array (\n";
foreach($params as $key=>$value) {
$paramsString .= "'".$key."' => '".$value."'\n";
}
$paramsString .= ")";
$logger->crit("ERROR = ".$this->view->message."\n"
."MESSAGE = ".$errors->exception->getMessage()."\n"
."STACK TRACE = \n".$errors->exception->getTraceAsString()."\n"
."REQUEST PARAMS = ".$paramsString);
