PHP security check

Is your website’s PHP safe to run?

We check whether your PHP version may be affected by known security issues—using plain language, not jargon. You can paste a version from your host, or try a website URL (when headers show PHP).

  1. 1 Run check
  2. 2 Understand
  3. 3 Fix & verify

Step 1 · Run a check

Paste your site URL or output from php -v on your server.

Please note: your IP address will be recorded when you run this check.

Read the Terms of Service

Don’t know your PHP version? Ask your hosting provider, or run php -v in SSH and paste the result here.

We never attack your site. If PHP is hidden, we say so—we don’t guess.

Step 2 · What does this mean?

Plain English: what the issue is, how serious it is, and why it matters for your site.

Complete Step 1 to see explanations here.

Step 3 · How to fix it

Numbered steps: backup, update PHP, test, and confirm the fix worked.

Fix instructions appear here after your check.
