我可以运行mysqli函数，而无需升级PHP版本5.4到7

Question

My requirement is bit odd... I have multiple doubts..

1. Could you please tell what are all the problems I'll face if I upgrade php5.4 to PHP 7? (on PHP 5.4 a process is already running, and I don't want to interrupt it)

2. Can I run mysqli functions, without upgrading PHP version5.4 to 7?

Answer 1

Yes, You can run. If your PHP version greater thank 5.3 you can run MysqLi. But I suggest you use PDO instead of MySqLi For more information please check the URL : http://php.net/manual/en/mysqli.installation.php
