PHPBench

Each iteration runs in a separate process, preventing cross-contamination and ensuring clean performance measurements, as highlighted in the README's feature list.

Uses revolutions and iterations to compute averages and aggregated data, providing robust insights into code performance over multiple samples.

Supports multiple output formats including console, CSV, Markdown, and HTML, allowing flexible result presentation and sharing, as shown in the screenshots.

Enables storage of baseline results and comparison to detect performance regressions over time, akin to PHPUnit but for performance metrics.
