mysqli + xdebug breakpoint after closing statement result in many warnings

Question

I have a piece of code like this:

$conn = new mysqli($host, $username, $passwd, $dbname);

...

$stmt = $conn->prepare(\'SELECT ...\');
$stmt->bind_par

What Alan wants to state is, that you can use these snippets the following way:

$stmt = $conn->prepare('SELECT ...');
$stmt->bind_param(...);
$stmt->execute();
$stmt->bind_result(...);
while($stmt->fetch())
{
    // do something here
}

// Disable the buggy interconnection between xDebug and PHP/MySQLi for a certain period
if (function_exists('xdebug_disable'))
              {
               $errorlevel=error_reporting();
               $displayerrors=ini_get('display_errors');
               ini_set('display_errors',0);
                error_reporting(0);
                xdebug_disable();
              }

$stmt->close();
unset($stmt);
unset($conn);

// finalle bring back the functionality
if (function_exists('xdebug_enable'))
              {
                xdebug_enable();
                error_reporting($errorlevel);
               ini_set('display_errors',$displayerrors);
              }

For me this also worked in PHP 5.6 And I use it as a workaround in https://github.com/joshcam/PHP-MySQLi-Database-Class

like so in MSQLiDB.php -> _dynamicBindResults():

/* BUG http://stackoverflow.com/questions/25377030/mysqli-xdebug-breakpoint-after-closing-statment-result-in-many-warnings 
           temporarily disable the buggy module interconnection         */
        if (function_exists('xdebug_disable'))
              {
               $errorlevel=error_reporting();
               $displayerrors=ini_get('display_errors');
               ini_set('display_errors',0);
                error_reporting(0);
                xdebug_disable();
              }
        /* Returning to normal xDebugging is only possible after $this->_mysqli->close
        if (function_exists('xdebug_enable'))
              {
                xdebug_enable();
                error_reporting($errorlevel);
               ini_set('display_errors',$displayerrors);
              }
         * 
         */
        $stmt->close();

Please note that I actually cannot reenable the xDebugging immediatly because this library destructs the MySQLi object very late. But that seems to be no reason for the debugger to stop showing debugging information :-> I had no time yet to figure out why.
