Re: [PHP] Why would a socket be unavailable?

[René Fournier]

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

There is another kind of blocking you could be running into (other

type mentioned in the manual) and it was eluded to before.  What are

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.)

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?
