PHP is used by almost 70% of websites

Who says it: Cloudflare; OpenAI ('an estimated 70%'); Wiz body text · Sources: Cloudflare OpenAI on X Wiz

None of the three cites the survey it comes from. A share of websites using PHP is an upper bound on exposure, not a count of vulnerable systems.

Fact-check

A2 Reported measures differently · Count · verdict: holds in part

Cloudflare, OpenAI and Wiz each state roughly 70%, but they restate one survey (Cloudflare links W3Techs; Tenable and Imperva name W3Techs), so this is an echo of one origin, and the survey's method is not captured, which caps a count at A2. The figure W3Techs publishes is a share of websites whose server-side language is known, a qualifier the claim drops.
