README.md

This repository contains scripts intended to benchmark operations of data structure classes from the PHP SPL extension against their array counterparts.

Requirements

  • PHP 5.4+
  • GD extension with FreeType support enabled

Installation

Clone the repository and use Composer to install dependencies.

git clone https://github.com/elazar/spl-benchmarks.git
cd spl-benchmarks
composer install -o

Usage

To invoke the benchmark runner, run this from the repository root directory:

./bin/spl-benchmarks

To learn about the runner's supported arguments:

./bin/spl-benchmarks --help

Results

By default, results are written to the results subdirectory of the repository root direction. All raw data is written in CSV format to raw.csv. Charts are generated in PNG format for executions per second and memory for each benchmark.

The results subdirectory also contains an index.html file for convenient viewing of all generated chart files.
