creating bak record in database causing fatal error

[Jimmi08]

Because this:

					if($sql->select('logstats','log_id',"log_id='".$datestamp."' ") && !$sql->select('logstats','log_id',"log_id='bak-".$datestamp."' "))
					{
						$sql->update('logstats', "log_id='bak-".$datestamp."' WHERE log_id='".$datestamp."' ");
					}

Double data are created:

And this is causing fatal error:

Fatal error: Uncaught TypeError: mktime(): Argument #6 ($year) must be of type ?int, string given in ***\e107_plugins\log\stats.php:1821 Stack trace: #0 ***\e107_plugins\log\stats.php(1821): mktime(0, 0, 0, '2021', '08', 'bak') #1 ***\e107_plugins\log\stats.php(212): siteStats->renderDaily() #2 ***\index.php(69): include_once('C:\\xampp8.0\\htd...') #3 {main} thrown in ***\e107_plugins\log\stats.php on line 1821

because explode fails on text "bak":

list($year, $month, $day) = explode("-", $date);
$date = strftime ("%A, %B %d", mktime (0,0,0,$month,$day,$year));
