Note Submitter: Luke at chaoticlogic dot net ---- Alright, I had a little error. I had one foreach() declaration, and then another foreach() declaration. They went: <?php //$connections is an array of Socket resources foreach ($connections as $key => &$value) { //the code here is impertinent } //$users is an associative array foreach ($users as $key => &$value) { //the code here is impertinent } ?> Alright, now, what error was produced as a result of this? This one: "Warning: Cannot use scalar value as array in filename.php on line 69." I then realized something; the reason for this came from the fact that I used $key, and $value for both of them in the exact same way. As a response to this, I've developed two ways to fix this: <?php //add this to the end of every foreach() you use unset($key,$value) ?> OR Simply use different variables for each one.
