How this comparison was built

Scores are medians across 1030 audited PHP sites and 8 audited Yii sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.

FAQ

Which is faster, PHP or Yii?
Based on real BeaverCheck audits, Yii sites score higher on Lighthouse performance (48 vs 46 on average).
Which has better security, PHP or Yii?
PHP sites score higher on security analysis (65 vs 62 on average).
Which has better accessibility, PHP or Yii?
Accessibility scores measured by Lighthouse WCAG 2.1 checks favor PHP (89 vs 88). Both technologies can be made fully accessible with care — the difference reflects common patterns in the sampled sites, not inherent platform limits.
Which is better for SEO, PHP or Yii?
PHP sites score higher on Lighthouse SEO signals (91 vs 91 on average), which cover meta tags, crawlability, mobile friendliness, and structured data. Content strategy and backlinks still matter more than platform choice for ranking.
Which has faster server response (TTFB), PHP or Yii?
Yii sites show lower Time to First Byte (248 ms vs 421 ms on average). TTFB depends heavily on hosting and CDN setup rather than the technology itself, but the sampled sites suggest a meaningful difference in common deployment patterns.
Should I choose PHP or Yii for my website?
Both platforms have trade-offs. Yii scores higher on overall composite score while PHP may excel in metrics you care about most. Run a free BeaverCheck audit on a real site using each to compare the metrics relevant to your use case.
