fpassthru maximum file size

[Anon]

what is the maximum file size for fpassthru and fread and how do i change it?

i have the following:

Header("Content-Type: application/octet-stream");
Header("Content-Disposition: attachment; filename=mdactypel25.exe");
$fp = fopen("/home/httpd/updates/mdactypel25.exe","r");
fpassthru ($fp);

the above file is about 7 mb and i get unexpected network error in lynx.
the code works just fine for files around 3mb.

btw... i'm runing redhat linux 7.0

Hmm...

I've never used passthru. Here is something I used about 2-3 months ago to work with a ~5mb file:

$fp = fopen("myfile.exe", "r");
while(!$feof($fp)) {
$buffer = fread($fp, 4096);
print $buffer;
}

basically i'm reading/writing in blocks. This worked for me, but I'm pretty sure fpassthru works maybe with some additional functions/parameters.

let me know if the above works,

Is it the file size, or is it perhaps the script is timing out? Perhaps a simple increase in the timeout value would help.
