the lzw_decompress functions & special characters?

It's just how Adminer / AdminerEvo is compiled from all its source files into this one - it's always been like this AFAIK.

I see here https://github.com/adminerevo/adminerevo/blob/6bb4d778cb2077889811727721253e14250eba8b/adminer/file.inc.php#L6

Do you know why the files are compressed?

To make them smaller ?

Seriously though, I don't really know why it is used here. It sounds like compressing and uncompressing on the fly is probably slowing things down and maybe impact opcache: https://tqdev.com/2019-lossless-compression-of-php-files

That article does mention obfuscation of source code, which I have seen used on several closed source PHP projects, but for this it doesn't make much sense to me because all the source code is open source. Maybe there is some other reason I am not aware of??
