stream_get_line behaviour Bug #63240

Hi! We switched from php 5.3.10 to 5.3.17 this weekend and stumbled upon a behaviour of stream_get_line that is most likely a bug and breaks a lot of our file processing code. The issue seems to have been introduced from 5.3.10 to 5.3.11. I opened a bug report: #63240. The issue seems to be related to #44607, but that one got fixed years ago. Is anybody able to confirm this behaviour or has stumbled upon this? Furthermore the behaviour of stream_get_line on an empty file seems to have changed between php 5.3.10 and php 5.3.11: <?php $file = __DIR__ . 'empty.txt'; file_put_contents( $file, '' ); $fh = fopen( $file, 'rb' ); $data = stream_get_line( $fh, 4096 ); var_dump( $data ); result in string(0) "" for php 5.3.10 and in bool(false) for php > 5.3.10. I don't know if this should be considered a bug, but as far as I know such a behaviour should not change during minor releases... Any insight is appreciated! Greetings Nico
