Hi,
I have this code (below) that waits for particular data to come over
the socket (ENX), at which point it breaks out of the loop and does
other things. Presently, it will loop forever, until it receives

Hi all,
Still encountering some challenges with my socket loop. Basically, I
need this socket client to wait to read incoming data, but if nothing
happens for more than three seconds, I want it to do something, then
return to waiting (for another three seconds). I've got some good help
I get this output:
PHP Warning: socket_read() unable to read from socket [35]: Resource

line 63
From this code:
do {
socket_set_block($socket);
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,$timeout);
The script doesn't even get that first while condition line. It loops
a few times (while receiving messages), then when no more messages are
coming from the server, and it times-out, it breaks out of the while,
then returns to the top again, where it that while condition returns
the error
There is no firewall. I'm running this locally.

it can send the server a ping (which I must do). THAT is where the
Hi,
I'm developing a PHP program that must send data, over a socket
connection, to a server. The server requires the data in a particular
format, e.g.:
FORMAT:
3-byte delimiter - Message Length (N = 4 bytes) - Message Type (4
bytes) - Message Body (N - 4 bytes) - 3-byte Delimiter
SAMPLE
I don't know C, but I was wondering if it is possible to:
1. Define 32-bit integer in PHP, called $val (max value of $val);
2. Assign the value of 10 to $val.
3. Pack $val to a binary variable ($bin_var);
...such that $val is only equal to 10, but it is occupying 32-bits of
data...

When reading from a Socket Server, my Socket Client retrieves data that

}

Hello everyone,
I really appreciate the suggestions so far with my socket client

All the examples I see of socket_select() are on socket servers. But is
it reasonable/feasible to use socket_select() on a socket client, that
is receiving data periodically from a server (and when not receiving,
doing something else)?

I'm looking for some good, secure login code, and found the following
article:

Not being much of a security expert, I was wondering if anyone here
could say whether this code is any good? Or if there's a better one
elsewhere?
The link I posted previously is causing me some grief, apparently
because I don't know the first thing about object-oriented PHP or PEAR.

your opinion?

resolution (500 pixels x 500

Is this something about signed versus unsigned integers? What I really
would like to do is convert that negative number (-71788), which I
suppose is unsigned
OK, that makes sense. But here's the problem: I receive binary data
from SuperSPARC (big-endian), which I need to unpack according to
certain documented type definitions. For example, let's say that $msg
has the value 3961595508 and is packed as an unsigned long integer
(on the remote SPARC).
Thanks. The fact that this behaviour is a bug somehow makes me feel
better. At least I'm not crazyor, not as crazy as I thought.
