Is there a way of getting the final size in bytes of the output of a php file? i have a separate php file that is doing the following... [code] print "filesize[" . filesize('roro3.flv') . "]"; [/code] which outputs... filesize[18492343] so that works fine... I want to get the FINAL size in bytes for the output of a php file... i tried this (which i was sure wouldn't work) [code] print "filesize[" . filesize('tracking.php?action=show') . "]"; [/code] You can see that file for youself here... http://triotalentagency.com/newsite/tracking.php?action=show but that code prints out this... filesize[] i also tried to use readfile() but that didn't seem to work.... is there anyway to do this? thanks!
