Trying to connect from XAMPP to Arduino on windows I found out that PHP-Serial couldn't open the device.

I solved the problem by following answer #13 at this link ( https://code.google.com/p/php-serial/issues/detail?id=7 ) .

Line 113 on PhpSerial.php was changed to

 $this->_device = "\\\.\com" . $matches[1];

Wondering if this is a Xampp-only issue.

whit php7.4(nts) on windows 11, it's the right way to solve this problem.thanks! But, why?
