Two Socket Questions

[Oni]

Hi--

I have two questions regarding sockets that I havent been able to find an answer to on the internet.

The first is that when Im transferring a file I get an error when the other side quits. This error makes the script fail. What should I do so that when the other side stops downloading the script closes the connection and keep on looping (listening). (error: socket_write() unable to write to socket 4 [32]: Broken pipe in...)

The other is about cpu usage.

$bufsize = 20000;
while($buf = fread($fh, $bufsize))
socket_write($spawn, $buf);
fclose($fh);

The files that will be transferred are around 175mb. Is the buffer size at a good value?

Thanks-

Consider using the more modern stream socket functions rather than the old (and not universally supported) socket_ functions.

This will give you the ability to use stream_copy_to_stream to serve files down a socket.

I dont feel confident using a function set that Ive never seen an example of on the internet... The comments on php.net arent helpful either.

So I tried to make my old code work, I think Im close but not quite there yet...

while(($buf = fread($fh, $bufsize)) && ($spawn))
while(($buf = fread($fh, $bufsize)) && (!feof($spawn)))

Two different tries, none of them worked...

Thanks for the comment tho-
