title: Is there a way to send tracking info to Google Analytics from PHP?
body: <p>I have a PHP code that will return a image. 
  the link is given to 3rd party.  so, i need to keep track where the php request coming from.  Because the PHP only return the image, I cannot use the Javascript code for Google analytics.
  I know that I can get the information from the access.log, but i think I can't dump the access.log to GA for analyzing, right?
  so, is there a way that I can do in PHP (e.g. sending a CURL ), send somethig to Google Analytics for tracking?</p>
