Question

I have a time consuming script, and I want to periodically log it execution time. How do I find out the current execution time?

Answer 1

The symfonian way to log execution times is using the timer manager that comes with symfony.

//Get timer instance called 'myTimer'.
$timer = sfTimerManager::getTimer('myTimer');
//Start timer.
$timer->startTimer();
// Do things
...
// Stop the timer and add the elapsed time
$timer->addTime();

This timer will be saved into any logger you have configured with your symfony.
By default symfony has the sfWebDebugLogger for the DEV environment but you can create your own and configure it in the factories.yml file.

The nice thing about this logger is that it logs also the number of calls to the timer.
