This is not happen in version 2.20.7 (file type php is supported yet in this version)

Thanks for raising this issue. Could you please send me the file (or a part thereof) that causes this issue?

[Ebta Setiawan]

this is just simple example php file: sample.php

Using command

minify -v sample.php -o sample-out.php

will raise runtime error

[Taco de Wolff]

This has been fixed in v2.20.10!
