Description:
------------
I read in Bug #29287 about breaking out of loops and was wondering if anyone considered breaking out of a generic compound block. This would satisfy the need for error handling without goto.

Example:
function connect() {

{ //start compound block

if (!mysql_connect('host', 'user', 'pass)) break; //break out
if (!mysql_select_db('database')) break; //break out
return;

}

$code = mysql_errno();
$msg = mysql_error();
throw new Exception($msg, $code);

}

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Adding this functionality would break scripts, so we'd need a new keyword which has issues...

A suggested work-around is like that:

if ($foo) {
    do {
        if (do_something()) {
            break;
        }
        do_more();
    } while (0);
}
