I will elaborate! –Ilia Rostovtsev Oct 27 '12 at 13:23 Do you have your error reporting turned on? –Ghazanfar Mir Oct 27 '12 at 13:23 Also try ..or die(mysql_error()); to get more information.. –intelis Oct 27 '12 at 13:24 2 @Ilia Rostovtsev: it doesn't matter. The problem is that the error reporting is turned off. Rajeev, turn on the error reporting then you will se what is the problem but please do not use the mysql_ stuffess, try PDO or mysqli_ –Peter Kiss Oct 27 '12 at 13:27 2 Please, don't use mysql_* functions in new code. They are no longer maintained and the deprecation process has begun on it. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which.

PHP Code: $link=mysql_connect("localhost",$connect['user'],$connect['pass']);
...which is as per the php on-line documentation. What it should do, I think, is try to connect to the database, and if the connection fails (for whatever reason), it
if(!$link)
{

header("Location:http://".$_SERVER['HTTP_HOST']."/fail.htm");
}
else

doing various scenario testing to make sure our application catches exceptions well, but I am unable to properly catch an exception when the database connection fails. I am using this as a test: try { \Database_Connection::instance()->connect(); } catch (\Database_Exception $e) { die('Database Connection Error: '.$e->getMessage()); } This is the result I get, showing there are some errors that I can't catch: Warning!

The others are PHP errors or warnings, which can't be caught. Day in the life of a PHP programmer, I'm afraid. These errors are all programming errors, and should be fixed long before the application reaches production state. We have chosen to not overload the core code with parameter validation, as it would only serve to protect from programmers error, but would make the framework slower at every request. nearo June 2012 I appreciate your response, as usual The thing is these are not application / programming errors, so there is nothing that I can fix. The scenario is this: The app works, without error, but if the mysql db is offline, the errors that I posted appear. There is no way for me to catch those errors, that I can find. Does that make sense? I want to catch those errors and display a nice message to the user, and not reveal the innards of the app. You can recreate this by putting that try catch block in your code, seeing that there are no errors, and then tur
