PHP Compare
Compare the output and performance of up to four PHP programs, directly in your browser.
- Playground
- PHP 8.4
- WASM
Compare output and performance
Edit a reference implementation, add up to three variants, then compare their output and execution time. Code, timings, and run details stay aligned so the trade-off is visible at a glance.
PHP 8.4, powered by WebAssembly
Each program runs in its own Web Worker through php-wasm. The runtimes stay isolated, while compact share URLs make the exact same setup easy to reproduce.
