When called on compressed data it will return an error. So doesn't seems to be doable. I propose to close as wont fix ------------------------------------------------------------------------ [2019-12-05 16:25:13] cmb@php.net Thanks for the explanation! I assume that zip streams are not seekable, because fseek()[1] has only introduced recently (and maybe zip streams are already seekable if ext/zip has been built against libzip >= 1.2.0?). Anyhow, that wouldn't be a bug, but rather a feature request. And yes, the current behavior should be documented anyway. I'll see to it, unless somebody else beats me to it.

Well, actually both of them. zip:// is not seekable, and if that's wrong then why it's not documented. Anyway, I am wondering to know why compress://zlib is seekable. Thx ------------------------------------------------------------------------ [2019-12-05 14:36:03] cmb@php.net What's the bug you are reporting? Is it that zip:// streams are not seekable? Or is it that this is not documented? ------------------------------------------------------------------------ [2019-12-05 13:54:11] arava dot box at gmail dot com Description: ------------ --- From manual page: https://php.net/wrappers.compression --- Test script: --------------- $sourceHandle = new SplFileObject('zip://file.zip#content.txt', 'r'); //... $sourceHandle->seek(PHP_INT_MAX); $sourceHandle->rewind(); // SplFileObject::seek(): stream does not support seeking ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78915&edit=1
