Unfragile

The request names jdorn/sql-formatter, which is a PHP SQL formatting library, but none of the candidate sources describe it; the closest real options for formatting or linting SQL are SQLFluff, which auto-fixes SQL style issues 111, and Pygments, which is a syntax highlighter rather than a formatter 515. Packagist 8 is a PHP package repository where the library would be listed, but its page does not show it as a formatter.

A question back: Do you want to keep using the PHP library jdorn/sql-formatter itself (for example, via Composer), or are you open to a different SQL formatting tool?
