PHP：die（）必须死吗？

Question

Is it considered bad practice to let die() live in a production enviroment? Just happened to read this article http://www.phpfreaks.com/blog/or-die-must-die where the author fies upon people who use such a thing in a production enviroment. So shouldn't I code this way:

$connection = mysql_connect($db_host, $db_username, $db_password);
if (!$connection){
    die ("Could not connect to the database.");
}

How do you code?

Answer 1

You don't die everytime you make a mistake, do you. Why should your application do?

the correct way is to intercept errors and process them in a context-dependent fashion, for example

try {
    application goes here

    $conn = mysql_connect(...)
    if(!$conn)
        throw ....
    ....
} catch(Exception $err) {
     if(PRODUCTION) {
        log error
        say something nice
     }
     if(DEBUG) {
         var_dump($err);
     }
}
