Hey all, I am having a situation where I have a singleton class with a static array in it. I insert an element into that array, and then I redirect the user to another page. At that page, I then retrieve that array (it's stored in the session vars), but the array is then empty when I retrieve it. I can't figure out why. Here are some pertinent code snippets. First, the class with the static array: class Logger { private static $instance = NULL; private static $messages = array(); //Private constructor to prevent this class from being instantiated multiple times private function __construct() { } //The clone function is private to prevent cloning of this class private function __clone() { } //Returns the singleton instance of this class public static function GetInstance() { if (!self::$instance) { self::$instance = new Logger; } return self::$instance; } public static function GetMessageCount() { return count(self::$messages); } public static function LogMessage($new_message) { self::$messages[] = $new_message; } public static function GetMessages() { return self::$messages; } public static function ClearMessages() { self::$messages = array(); } } Here is the code where I insert something into the aformentioned array (the process is that a user tries to log in, but the login fails, and so we insert a message into the array saying that the login credentials failed). //Retrieve the message logging instance from the session data to be able to pass messages to the user. $message_log = $_SESSION['user_messages']; $user = $_SESSION['user_account']; //Create a new instance of the database management class and //try to connect to the database $dbm = new DBM(); if ( !$dbm->isConnected() ) { $message_log::LogMessage("We are sorry, but we are unable to access the database at this time. Please try again later."); } else { //Retrieve the user login information $useremail_dirty = $_POST['useremail']; $password_dirty = $_POST['userpassword']; //Check to see if the email we were given exists in the database, and if the password matches $doesPasswordMatch = $dbm->doesPasswordMatch ( $useremail_dirty, $password_dirty ); if ( $doesPasswordMatch ) { //Correct login information was received. Login the user and redirect appropriately. $user->Login(); header ( "Location: ".BASE_URL."/userpage.php" ); exit; } else { //If an incorrect email or password was given, report that information to the user. $message_log::LogMessage("Incorrect login information."); } } //The user has failed to login. Redirect to the appropriate page. header ( "Location: ".BASE_URL."/loginfailed.php" ); And finally, given an unsuccessful login attempt, this is where I pick back up the array of messages to display the messages to the user: $message_log = $_SESSION['user_messages']; $all_messages = $message_log::GetMessages(); print $message_log::GetMessageCount()."<br>"; print count($all_messages)."<br>"; foreach ($all_messages as $message_string) { $prepared_string = prepare_text_for_html_output($message_string); echo $prepared_string."<br>"; } $message_log::ClearMessages(); Unfortunately, the "all_messages" variable has nothing in it...it's like the messages that I logged in the previous PHP script never even existed. I am calling session_start, so don't worry about that (even though it's not seen in these code snippets). What could be going wrong?

Okay, so this problem will seem a little convoluted at first, so try and keep up I am running a PHP script which is doing some updating to our SQL database. Every so often this PHP script will output its status, and all-in-all it takes about 1 hour for this script to finish the work that it is does. We have a test server and a production server. When I run this particular script on our test server, it will run perfectly for about 45 minutes, and then suddenly it will give me an error stating: "Fatal error: Maximum execution time of 30 seconds exceeded in importusers.php on line 235" First of all, I didn't know that there was a maximum execution time for PHP scripts to run. Second of all, why would it give me this error saying that it had exceeded the 30 second limit if it is already 45 minutes into the process? It doesn't make much sense to me. Anyways, I ran phpinfo() and checked where the php.ini file that it references is. It is in the "/etc/" directory. I went there and edited the max_execution_time variable to be 300. I then restarted the server and ran phpinfo() again. But according to phpinfo() the max_execution_time is still 30 seconds! How can that be? I know I edited the correct php.ini file, and I have it open in front of me right now. It says 300 seconds. How could the php.ini file and phpinfo() disagree? Anyways, all of that is just the problems I am having on the test server. Now we come to the production server: Whenever I run this same script on the production server, I simply don't get any output. If you remember, I said that the script outputs its status every once in awhile so that I know how things are going. Well, running it on the production server it simply doesn't give me any output at all! However, when I place random "exit" statements throughout the PHP script to see what is going on, it will output stuff as it exits. Why is it doing this? How can I get it to do the output on the fly on the production server? (I am calling flush() after every echo and print statement.) So, all in all, I need to somehow fix this 30 second issue on the test server (and possibly on the production server...I can't tell because there is no output) and the output on the production server. Any advice?
