Nifty feature is that you don’t have to worry about turning off debug on production version of your website. Simply populate $ips array with IP addresses you are using and debug will be displayed only to you.

To display mysql errors in this debug, use trigger_error function (example trigger_error($sql.’ ‘.mysql_error($link) ,’DB_ERROR’);)

$ips = array('127.0.0.1','88.99.109.119');
set_error_handler("ErrorHandler");

function ErrorHandler($errno, $errstr, $errfile, $errline)
{
	global $error_handler;

	if (preg_match("/DB_ERROR/iUs", $errno))
	{
		$error_handler[] = "DB_ERROR* $errstr\n" . "Fatal error on line $errline in $errfile";
	}

    switch ($errno) {
   	case E_ERROR:
    case E_USER_ERROR:
        $error_handler[] = "E_USER_ERROR $errstr on line $errline in $errfile. $errstr\n";
        break;

    case E_WARNING:
	case E_USER_WARNING:
        $error_handler[] = "E_USER_WARNING on line $errline in $errfile. $errstr\n";
        break;

    case E_NOTICE:
	case E_USER_NOTICE:
        $error_handler[] = "NOTICE on line $errline in $errfile. $errstr\n";
        break;

	case E_PARSE:
        $error_handler[] = "E_PARSE on line $errline in $errfile. $errstr\n";
        break;

	case E_STRICT:
        $error_handler[] = "E_STRICT on line $errline in $errfile. $errstr\n";
        break;

	case E_DEPRECATED:
        $error_handler[] = "E_STRICT on line $errline in $errfile. $errstr\n";
        break;

    default:
        $error_handler[] = "UNKNOWN on line $errline in $errfile. $errstr\n";
        break;
    }
    return true;
}

function smarty_function_module($params, &$smarty)
{
	/* Check if required params are valid */
	if (!isset($params['class']))
	{
		$smarty->trigger_error('Module name is not defined!');
		return false;
	}
	if (!isset($params['method']))

		return false;
	}

	return call_user_func($params['class'].'::'.$params['method'], $params);
}

Example usage:
{module class=”CLASS_NAME” method=”CLASS_METHOD_NAME” param1=”string1″ param2=77}

Your class method will receive one parameter (associative array), which will contain all parameters passed to smarty function. I this example array would look like this:

Array
(
    [class] => 'CLASS_NAME'
    [method] => 'CLASS_METHOD_NAME'
    [param1] => 'string1'
    [param2] => 77
)

To install this plugin simply create file named function.module.php in smarty plugins folder and copy&paste function to that file.

There has been a lot of discussion on GOTO statements during the years most of them citing “Goto considered harmful” [uri]. Even with all those comments and articles on GOTO I still haven’t heard argument against it that doesn’t resolve to “it looks ugly and breaks the flow” at the end.

Sure, there will be a lot of beginners that will use it wrongly… but it is still very useful when breaking out of a nested loop or nested if statements. If you ask me I am all for it.

Now a bit about implementation… we will probably see reuse of break keyword instead of goto. Reason for this is that a possible php GOTO is not a real GOTO construct. Break keyword would be extended with “static label”:
Cite:

for ($i = 0; $i < 9; $i++)
{
        if (true) {
                break blah;
        }
        echo "not shown";
blah:
        echo "iteration $i\n";
}

One of limitations that was discussed (to stop misuse) was restricting the construct so that you can only jump out of a construct is possible… (one example of misuse would be jumping to beginning of foreach() loop).

Another interesting thing was that ifsetor will probably not be introduced.

AWN doesn’t make permissions for config folder like it should, owner is root instead of you (the rightful owner). Quick fix is:

sudo chown -R $USER:$USER /home/$USER/.config/awn

I am sure this will be fixed very soon, till then have fun.

Every time you download sql countries list it will be up to date for that very minute. This is because it is fetched and parsed from ISO.org just for your pleasure, every time you download (well if you don’t mind a bit of caching :P)
