A PHP benchmarking framework for performance testing, analogous to PHPUnit but for measuring execution time and memory usage.
PHPBench is a benchmark runner for PHP designed to measure and analyze the performance of PHP code. It provides a comprehensive framework for performance testing, allowing developers to track execution time, memory usage, and detect performance regressions over time. It follows a testing-oriented approach similar to PHPUnit, focusing on performance metrics rather than functional correctness.
PHP developers and teams who need to systematically measure, monitor, and optimize the performance of their code, particularly those working on libraries, frameworks, or applications where performance regressions are a critical concern.
Developers choose PHPBench for its robust, process-isolated benchmarking framework that offers detailed statistical analysis, customizable reporting, and baseline comparison features, making it a specialized tool for performance regression testing akin to how PHPUnit handles functional testing.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
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.
Process isolation for each iteration adds execution time and resource usage, making benchmarks slower and less suitable for quick feedback loops.
Requires understanding of benchmark annotations and configuration, which can be complex compared to simpler timing tools, despite the documentation.
While it works with CI/CD, it may lack seamless plugins for all modern development environments, requiring custom setup for full workflow integration.
