Problem using readfile()

Anon

Hi,
I'm using readfile to send a file. The code is:

header("Content-length: $size");
header("Content-type: $type");
header("Content-disposition: attachment;filename=$filename");
readfile($filename);

It works for very small files, but for larger files it seems to send the first 600 bytes and then hang... I tried with both IE and Netscape and have the same problem. I'm using Apache 1.3.14 and PHP/4.0.4pl1 on Win2000.

Any hints appreciated. Thanks.

are you using "rb" mode in open file?

readfile() doesn't take any mode arguments, I think you were thinking of fopen(). But thanks anyway 🙂

I have exactly same problem. I've tried fopen() too but it didn't work either. If somebody could help. I am really stuck here.

Any help appreciated.

I managed to solve this problem.

readfile() won't work you have to use fopen.
Like this

$fn = fopen($path,"rb");
fpassthru($fn);

At fopen that 'b' is really important on windows system! It won't work without that.

How big were the files that you were using to test this with? This method gave the same results as readfile() for me when trying a 30MB file, I ended up with a 17MB file written. Could it be timing out at the server end and simply disconnecting me?
