The problem is that in the below function, the code within the [[[if > (file_exists($dirty_file_path))]]] does not get run if I change [[[$dirty_file_path]]] to > "php://memory".

Thank you. what does it matter that it runs slowly, run it once and be done with it? alternatively use the php tidy extension and avoid the file system and shelling out altogether. actually I'd imagine shelling out from a webserver process is the bottle neck and not saving/reading from the file system. lastly I don't suppose you've heard of /dev/shm ? and, er, no, I don't have experience with php://memory but you might try searching for other people's code: http://www.google.com/codesearch?q=php%3A%2F%2Fmemory&hl=en&btnG=Search+Code > //========================================================== > function cleanUpHtml($dirty_html, $enclose_text=true) { > > $parent_dir = "/filesWrittenFromPHP/"; > $now = time(); > $random = rand(); > > //save dirty html to a file so tidy can process it > $dirty_file_path = $parent_dir .
