[PHP] Sockets
Hey everyone, Does anybody know what the current support / functionality for PHP with sockets is? According to the documentation, all the socket_ functions should be included in PHP >= 4.1.0. I'm currently running 4.2.1 and PHP doesn't seem to recognize these functions (socket_send, socket_write, etc). Anybody know if there's anything special I have to do to get it working? // Asmodean -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Let's assume you've set your session timestamp (assume it's called
$session_time) to time() at the time of login. Now, in the script...
if ((time() + 300) > $session_time) {
}
This would be a check to see if the session is still valid. Timewise.

Wrong. My fault. ;)
It's...
if (time() > $session_time + 300) {
}
Sorry.

Yes. time() returns a UNIX timestamp (currently a 10-digit number)
representing the number of seconds since a certain date (sometime in
1972).

Assuming you have an array of colors called $color (and assuming I
haven't misread or misinterpreted any information), you can do the
following to directly print your colors.
// Prints out all colors comma-separated.
print(join(", ", $color));
// Prints out all colors linebreak-separated (HTML-wise).
print(join("", $color));

How do you mean remove? Do you mean you want to include the file
html.html but not the "..." part? And why?

Seems like a... strange thing to do. Anyway. Since I do not know of
any other way (if there is, anyone, tell), this is what you will have
to do.
1. Open the file with fopen()
2. Perform a regular expression on the content
3. Print the parsed cntents
For example:
$fp = fopen('html.html', 'r');
$content = fread($fp, filesize(html.html));
preg_match("/(.*?)<\/body>/s", $content, $matches);
The parsed contents are now in $matches[1].
I still don't understand why you want to do this, though. Seems like
there must be a better way.

Your problem is with this line. Look closely at the following part:
name=\"choice",$count,"\"
You should do this:
name=\"choice" . $count . "\"
... and it will generate names like 'choice1', 'choice2', and so on.
