Hey

I have a script that I am trying to figure out to allow a remote file to
be sent to a client's browser. It works ok for small files, but it keeps
timing out for large files. I don't think it should even take as long as
it does (i.e. about 10seconds) before it pops up a dialog box for me to
download a 700KB file. Any ideas? It times out on a line around which reads

while (!feof($fp))
{
$tmp .= fread($fp, 64);
}

Thanks

Well you're still reading the file (or url or something) at this point.
Is it the reading of the file or sending it to the browser that fails?

A bit of context might for this code too. Is this reading a local
file or url or what?

If it's a local file, use fpassthru (http://php.net/fpassthru) if it's
not too big. If it is a big file then use your loop but don't store it
in a $tmp variable, just output it.

Your script is reading the whole file, 64 measly bytes at a time, into
a monstrous string $tmp.

Then, finally, when you've loaded the whole [bleep] file into RAM in
$tmp, you just echo it out, right?

Don't do that.

:-)

while (!feof($fp)){
echo fread($fp, 2048);
}

You can play around with 2048 versus 64 versus 1000000 on your box to
see what's "fastest" but I'll be pretty shocked if 64 bytes is the
best performer...

Yeah, I get a buck. So?

And if the OP is opening the file anyway, he might as well use
readfile() instead.
