README 文档

README

This small tool is being build to statically analyze your code for potential performance issues.

Installation

composer require --global "php-cost-estimator/php-cost-estimator"
cd /your/project
estimate-cost estimate-cost:initialize

Usage

cd /your/project
estimate-cost

Output

The higher the number the more likely it is that the code is causing performance issues.
