PHP Download Script Problems
| Posted by kyriakos, 07-21-2008, 05:19 PM | | I've tried some of the scripts on the manual page of readfile function of php on php.net for example:
My problem is that even though the download works fine, no matter what browser i tried it with it doesnt show up the file size and consequently the users of my site cant know how far in a download they are or if they got the full file or not. I believe its a web server setting causing this since the code seems to work for others. anyone has any idea what might be causing this?

| Posted by kyriakos, 07-21-2008, 06:00 PM | | i already do that (check the function above) still the same outcome.

Why the:
ob_clean erases the output buffer.

Also, readfile is terribly inefficient since it loads the entire file in RAM and does not support HTTP range requests (resumes or download managers that use lots of connections).
I could post some efficient code that works but I'm not allowed to yet (need 5 posts!)

tonyhark could you send me a private message with it ?

the problem with such a script now is.. how would i know when the download was actually finished in order to increase my download counters? its pretty important to count 'actual' downloads than initiated downloads.
