I'm saying, you can see the line reading/byte reading behavior if you switch the stream to read lines. There is a bug here. ------------------------------------------------------------------------ [2019-04-01 08:21:36] alexey dot khokhryakov at gmail dot com I tried and I see that my test script works but it breaks SplFileObject::fread() functionality as I said. file_put_contents($tmpFilename = tempnam(sys_get_temp_dir(), 'test'), "one\r\ntwo\r\n"); stream_wrapper_register('foo', FooStreamWrapper::class); $file = new SplFileObject("foo:/{$tmpFilename}", 'r'); var_dump($file->fread($file->getSize())); Expected: string(10) "one two " Actual: string(5) "one " ------------------------------------------------------------------------ [2019-04-01 08:12:40] requinix@php.net Try the change I said, see what happens. ------------------------------------------------------------------------ [2019-04-01 07:38:58] alexey dot khokhryakov at gmail dot com requinix@php.net, I don't think so. If wrapper::stream_read() proxies calls to fgets() then SplFileObject::fread($count) becomes inconsistent because PHP's file wrapper returns $count of data including linebreaks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
