Does PHP have built-in debugging logging like Ruby on Rails logger.info() to a development.log file?
<p>Does PHP have built-in debugging logging like Ruby on Rails logger.info() to a development.log file?</p>

<p>With PHP I'd like to look "under the hood" to see what's going on... pages served, query string values, etc.</p>

<p>I've Googled a bunch but can't find anything.</p>

<p>(I'm trying to port a web app from RoR to PHP because I need more execution speed.)</p>
