How to include map.php as a source of an img tag

I am displaying a map in my page, in static PHP it is something like (img src="action/map.php") as all the code regarding map is in map.php.

In Symfony, I am getting confused where to put my map.php fil开发者_如何学Ce and how to include that file as a source of an img tag.

you could get it done with e.g. an action:

public function executeShowmap(){
  $this->getResponse()->setHttpHeader('Content-type', 'image/jpeg');
  $this->getResponse()->setContent(file_get_contents($filename));
  return sfView::NONE;
}

and in the view:

img src="<?php echo url_for('module/showmap'); ?>"
