Description
Description
Currently, when writing to a gz file using the compress.zlib:// protocol wrapper it is not possible to pass the mtime or name of the original file. It would be nice if we could do so without having to reopen the gzip file in write mode for write the metadata directly into it as in this bug report https://bugs.php.net/bug.php?id=46577
I believe that this can be done by adding new stream context options for zlib (similar to those for phar). See https://www.php.net/manual/en/context.php
The gzip file format supports the following meta data:
- compression method
- itype (text or binary)
- mtime (nice to have)
- size (thankfully set by compress.zlib:// )
- os
- original file name (nice to have)
- comment

Research direction
Start by inspecting the compress.zlib:// protocol wrapper and its stream context option handling, then compare the existing phar context options referenced in the issue. Determine how mtime and original file name should be passed into gzip metadata, and verify that writing through the wrapper preserves both values without reopening the file.
