The PHP versions powering the WordPress domains we've scanned (grouped by major.minor), alongside how each group scores across our infrastructure security checks. Versions marked EOL are end-of-life and no longer receive security patches — running an unsupported version introduces significant security risk. Data is parsed from the X-Powered-By HTTP header, covering domains that expose version details; metric coverage expands continuously as domains are rescanned.

Coloured against the all-WordPress average — green beats it, red is worse. Site counts use TLDWP's canonical detected population; percentages use the corresponding cached security sample. Click a column to sort.
