this is a little reference from my live chat script, but it wont work. The error message is variable $con is not defined, but it is clearly defined.

 

$con = mysqli_connect("localhost","root","123","chat") or die(mysqli_error($con));function get_msg(){ $query = mysqli_query($con, "SELECT Sender, Message FROM chat"); $run = mysqli_query($con, $query); $messages = array(); while($message = mysqli_fetch_assoc($run)){ $messages = array('sender' => $message['Sender'], 'message' => $message['Message']); } return $messages; }

In PHP global variables are not accessible from inside functions unless you use the global keyword or $_GLOBALS array. You can read about variable scope here: http://es1.php.net/manual/en/language.variables.scope.php
