I am wanting to write an internet 'server' program. For ease, I want to use
PHP-CLI with XINET super server.
XINET communicates with the 'server' program via STDIN/STDOUT.
I'm not sure how to communicate with the client this way though.. I can open
stdin/out as a file, and use read and write operations, as if it were a
regular file.. however, how can I set read timeouts on file read operations?
Basically what I want is:
- send binary data to the client
- read binary data from client, but with a timeout of 1 second.
So I want a 'blocking' read operation, but one that doesn't block forever,
but times out.
I know how many bytes I expect when doing a read operation, so perferably I
tell the read operation how many bytes to read.. if it is not received
within x seconds, it should time out.
How can this be done in PHP?
I think I have seen examples where somehow the STDIN/OUT is communicated
with by using socket read/write operations, but I have no clue how this is
done.. the advantage would be that the socket timeout functions could be

Re: how to set Read timeout ?
set_time_limit(5); // 5seconds timeout for php
$start_time = time();
$valid_read = read_data("$filename"); /* return 0 on error, 1 if
$end_time2 = time() - $start_time;
echo "total executution time = ".$end_time2;
Good luck !
