Re: Why would a socket be unavailable?

There is no firewall—it's all running locally, on my iBook (with Firewall off). You know, I really wish it WAS the firewall. :-) I really can't believe this little problem I'm encountering is because of some bug in the Socket library. I mean, what I'm doing is so simple, and I'm sure hundreds of other PHP programmers have done this before, like, a million times. The whole script is actually very simple: Enter loop If data is received, handle it If data is not received in several seconds, send server a ping ...Rene On Thursday, May 13, 2004, at 05:40 PM, Vail, Warren wrote:

There is another kind of blocking you could be running into (other than the type mentioned in the manual) and it was eluded to before. What are the odds you are going through a firewall to get to the server. Firewalls will reject attempts to connect to unauthorized sockets on protected machines.

Yes, I've read that page... many times. It has not helped me. That is why I am posting my problem here, in that hopes that someone can help. (I don't mean to be completely helpless, but I just don't yet understand blocking/non-blocking sockets, and the parameters associated, since they are not well-documented. Someone said I shouldn't complain about this-and I'm not-since the functions are marked "Experimental". But this is precisely why I'm posting the question here.) .Rene

I just read something about sock warnings this morning. It said sometimes they drop off, and to ignore the warnings, but capture the errors.

I get this output: PHP Warning: socket_read() unable to read from socket [35]: Resource temporarily unavailable in /Users/rene/Sites/gpspolice/titan/cr.php on line 63 From this code: do { socket_set_block($socket); socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,$timeout); while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) { [...] And it's failing at "while". Any ideas? ...Rene
