How to use Zend_Log

Setup the logger in the Bootstrap file:

view plainprint?

1.    
2. //initiate the logger - Log to a file  
3. $writer = new Zend_Log_Writer_Stream($root.'\log\test.txt');  
4. $logger = new Zend_Log($writer);  
5. //Log to Database.  
6. $columnMap = array('lvl' => 'priority', 'msg' => 'message', 'timestamp' => 'timestamp', 'lvlName' => 'priorityName');  
7. $dbwriter = new Zend_Log_Writer_Db($db, 'log_table_name', $columnMap);  
8. $logger->addWriter($dbwriter);  
9. //Log to firebug  
10. $writerFirebug = new Zend_Log_Writer_Firebug();  
11. $writerFirebug->setPriorityStyle(6, 'TRACE');  
12. $logger->addWriter($writerFirebug);  
13. $registry->logger = $logger;  

 
//initiate the logger - Log to a file
$writer = new Zend_Log_Writer_Stream($root.'\log\test.txt');
$logger = new Zend_Log($writer);
//Log to Database.
$columnMap = array('lvl' => 'priority', 'msg' => 'message', 'timestamp' => 'timestamp', 'lvlName' => 'priorityName');
$dbwriter = new Zend_Log_Writer_Db($db, 'log_table_name', $columnMap);
$logger->addWriter($dbwriter);
//Log to firebug
$writerFirebug = new Zend_Log_Writer_Firebug();
$writerFirebug->setPriorityStyle(6, 'TRACE');
$logger->addWriter($writerFirebug);
$registry->logger = $logger;
