How to Learn PHP Version
You have 3 choices.
- If you have access to FTP, please extract this file into your root and then visit yoursite.com/phpinfo.php address. You'll see the version info at the top of the page.
- Install this plugin: https://wordpress.org/plugins/health-check/ (When you activate it you get a message at the top of the plugins page.)
- Ask to your hosting provider or login your hosting control panel (if exists) and you should see it over there. There must be "PHP Settings" or that kind of button/link.
