Opening Keynote: PHP in 2018
summary
History of PHP leads to concrete 7.3 changes: flexible heredoc, trailing commas in function calls, monotonic timer hrtime, FPM get_status, is_countable, key_first/key_last and PCRE2 upgrade. Benchmarks at Etsy show ~10–15% faster and lower latency versus older 7.x, and optimizer work (DCE/SCCP) removes dead code in opcache. Practical tools demonstrated include the static analyzer Phan for precise type/shape errors and the low‑overhead profiler PHP Spy that generates flame graphs from running processes.
