There is no composite Writer object. However, a Log instance can write
to any number of Writers. To do this, use the addWriter()
method:
<?php
$writer1 = new Zend_Log_Writer_Stream('/path/to/first/logfile');
$writer2 = new Zend_Log_Writer_Stream('/path/to/second/logfile');
$logger = new Zend_Log();
$logger->addWriter($writer1);
$logger->addWriter($writer2);
// goes to both writers
$logger->info('Informational message');
