Isolated to https://3v4l.org/gTXsR, seems like a PHP bug.

@JanTvrdik I thought it has been solved but it's still failing on 3v4al.org. Did you report PHP bug? I can't find any open or solved.

@milo I don't remember opening any bug so it's possible that it has never been reported.

Just found in PHP documentation

If you have opened the file in append (a or a+) mode, any data you write to the file will always be appended, regardless of the file position, and the result of calling fseek() will be undefined.

But in doc of fopen()

a - Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it. In this mode, fseek() has no effect, writes are always appended.
a+ - Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it. In this mode, fseek() only affects the reading position, writes are always appended.

The a+ mode is about read/append. How would one can read.

I'll open PHP bug/doc issue.

As I expected, it is a problem of lower layer. So, documentation issue.

Is a good idea to emit notice by FileMock::stream_seek() in a+ mode? IMHO yes, it may notice programmer about this clumsy behaviour.
