SqlFormatter is a PHP class designed for formatting SQL statements. It automatically adds indentation and line breaks, enhancing readability and making SQL code easier to debug. It addresses the common issue of debugging auto-generated SQL by providing a simple formatting solution. The class is inspired by solutions found on Stack Overflow and aims to be lightweight and easy to integrate.
This project distinguishes itself through its ability to correctly split SQL strings into multiple queries using a tokenization approach, overcoming limitations of regular expression-based splitting. It offers flexibility with options for syntax highlighting only, compression for command-line use, and comment removal. The class is designed to be lightweight and avoids relying on large external dependencies.
