console.log, console.error for PHP?
<p>When developing web applications, at the clientside level I use console.log and console.error to help me see what's going on.  I am looking for a similar feature at the serverside level to help me see what's going on.  I have seen error_log which writes errors to the server's log file and wanted to know if there is a similar function for writing to the servers access logs?</p>

<p>Or am I going about this the wrong way, am I supposed to be using something completely different to see what's going on in the background for serverside development?</p>
