As to your other comment on the list about the bool(false) return instead of an empty string for an empty file, that was a bug fix. A return of "" would indicate an empty line. The result is now corect: $ php -r '$fd = fopen("php://temp", "r+"); var_dump(stream_get_line($fd, 10, "MM"));' bool(false) $ php -r '$fd = fopen("php://temp", "r+"); fwrite($fd, "MM"); rewind($fd); var_dump(stream_get_line($fd, 10, "MM"), stream_get_line($fd, 10, "MM")); string(0) "" bool(false) ------------------------------------------------------------------------ [2012-10-09 09:02:54] datib...@php.net Added a patch that will apply to 5.4.4 ------------------------------------------------------------------------ [2012-10-09 09:02:18] datib...@php.net The following patch has been added/updated: Patch Name: getrecord-delimiter-search-fix Revision: 1349773338 URL: https://bugs.php.net/patch-display.php?bug=63240&patch=getrecord-delimiter-search-fix&revision=1349773338 ------------------------------------------------------------------------ [2012-10-09 03:35:35] datib...@php.net Reduced test: $file = __DIR__ . '/input_dummy.txt'; $data = str_repeat( '.', 8189 ) . 'MMMM'; file_put_contents( $file, $data ); $fh = fopen( $file, "rb" ); $delimiter = "MM"; stream_get_line($fh, 4096, $delimiter); stream_get_line($fh, 4096, $delimiter); if ($delimiter === stream_get_line($fh, 4096, $delimiter)) { echo "BROKEN"; } else { echo "OK"; } fclose($fh); unlink($file); The amount of dots seems to be related to the used buffer length: (<number-of-dots> + 3) % (<buffer-length> x 2) == 0 The length of the delimiter also seems to play a role, but I'm not sure what that would be. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
