获取 Monolog 以登录到数组

Question

We have an old Application part which does not use Monolog yet. This application needs on one time the whole output from the log so it can print it out in a hidden div visible only for developers.

Much like live debug...
The problem is I can't figure out how to get Monolog to log to an array or set the handler for a local variable, or to get the output from the log on a particular part of code.

This is what I came up with until now:

 protected function getHandlers()
    {
        $handlers = array();

        $logsDir = $this->getLogsDir();
        $logFile = $logsDir . DIRECTORY_SEPARATOR . 'application.log';

        $logfileHandler = new \Monolog\Handler\FingersCrossedHandler($logFile, Logger::ERROR);

        array_push($handlers, $logfileHandler); 
        

        // When in CLI, we're going to push the logs through STDERR as well
        // This way, if needed, we can easily redirect STDERR to STDOUT or to some specified file
        if (php_sapi_name() == 'cli') {
            $stderrHandler = new StreamHandler('php://stderr', Logger::INFO);
            array_push($handlers, $stderrHandler);
        }

        return $handlers;
    }

Anyone any idea which handler is suitable for that? (examples are welcome)

Ok for thouse who have the same logical columdrum. I did it with a custom custom handler:

<?php

namespace Log\Handler;

use Monolog\Logger;
use Monolog\Handler\AbstractProcessingHandler;

/**
 * Description of runtimeHandler
 *
 * @author Sinisa Culic  <sinisaculic@gmail.com>
 */
class RuntimeHandler extends AbstractProcessingHandler
{

    protected $log;

    /**
     * @param integer $level  The minimum logging level at which this handler will be triggered
     * @param Boolean $bubble Whether the messages that are handled can bubble up the stack or not
     */
    public function __construct($level = Logger::DEBUG, $bubble = true)
    {
        parent::__construct($level, $bubble);
    }

    /**
     * {@inheritdoc}
     */
    public function close()
    {
        return $this->log;
    }

    /**
     * {@inheritdoc}
     */
    protected function write(array $record)
    {
        $this->log[] = $record;
    }

}
