Earlier this week, a critical security flaw in PHP was published. PHP runs a huge share of websites, including every WordPress site, and this flaw lets attackers take over the server. If your site runs PHP, it needs an update.

I noticed that most people don't know whether their site uses PHP, so I built doiusephp.com for them. Type in your website and within seconds it tells you:

• Whether your site runs PHP, and through what technology (e.g. WordPress or WooCommerce)
• Which PHP version your site uses and whether that version is already fixed (if your site shows it)
• What to do next, depending on who is responsible for your site

It also writes a short, personalized message you can copy and send to your web developer or host, so you don't need to dive into the technical details yourself.

The tool is free, needs no sign-up, and doesn't save anything about you or your website.

Hope this helps!
