我的网站的日志系统

Question

I create a small class for save the logs of my website. My log class :

class Logs {

public static function  writeFile($message)
{
    $log_path = '/home/vagrant/Workspace/symfony/app/logs';
    // Set path:
    $log_path .= '/' . date('Ymd');
    $log_path .= '.log';
    $s_message = date("Y-m-d H:i:s") . ' (' . microtime(true) . ') ' . $message;
    $s_message .= "\n";
    file_put_contents($log_path, $s_message, FILE_APPEND);
}
public static function logInfo($s_message)
{
    self::writeFile($s_message);
}

}

And I call the static method in my controller :

public function indexAction()
{
    $em = $this->getDoctrine()->getManager();
    $categories = $em->getRepository('EnsJobeetBundle:Category')->getWithJobs();
    $test = array(
        '1'=>'1',
        '2'=>'2',
        '3'=>'3'
    );
    Logs::logInfo(print_r($test));

    return $this->render('EnsJobeetBundle:Job:index.html.twig', array(
        'categories' => $categories
    ));
}

The problem is that : in my view it's show this $test array and in my log is write only the first value of array, so the value 1. What I'm doing wrong? Help me please! Thx in advance!

Answer 1

In accordion with the doc :

If you would like to capture the output of print_r(), use the return parameter. When this parameter is set to TRUE, print_r() will return the information rather than print it.

Use this:

Logs::logInfo(print_r($test, true));

instead of:

Logs::logInfo(print_r($test));

hope this help

I suggest you to use Monolog for this task

Answer 2

print_r has second parameter: return . Wich means will print_r() returns it's output, or just display it. It's false by default

So you need to try

  Logs::logInfo(print_r($test,true));
