Tested this with PHP v5.2.6 on Windows 2008 Server and FreeBSD 7.0 and it still returns incorrect results.

Location in stream: 15000 Attempting fix... Location in stream: 9307 Rewinding... Location in stream: 9307 ------------------------------------------------------------------------ [2008-04-02 11:56:25] amoo_miki at yahoo dot com Description: ------------ On some occasions stream_get_line acts weired by attempting the first seek without considering the "end of line" string. Below is the sample code that shows the problem with a workaround to temporarily solve the issue (that might ring some bells for the person who plans on fixing this). The code uses a small binary JPX file that can be fetched from http://barahmand.com/streambug/sample.txt Reproduce code: --------------- <?php $filename = 'sample.txt'; $arr = explode('<EndOfFrame>', file_get_contents($filename)); echo "Found in source at ".strlen($arr[0])."\n\n"; $fp = fopen($filename, "rb"); stream_get_line($fp, 15000, "<EndOfFrame>"); echo "Location in stream: ".ftell($fp)."\n"; echo "Rewinding...\n"; rewind($fp); stream_get_line($fp, 15000, "<EndOfFrame>"); echo "Location in stream: ".ftell($fp)."\n"; rewind($fp); echo "\nAttempting fix...\n"; stream_get_line($fp, 1, "<EndOfFrame>"); stream_get_line($fp, 15000, "<EndOfFrame>"); echo "Location in stream: ".ftell($fp)."\n"; echo "Rewinding...\n"; rewind($fp); stream_get_line($fp, 15000, "<EndOfFrame>"); echo "Location in stream: ".ftell($fp)."\n"; fclose($fp); ?> Expected result: ---------------- Found in source at 9295 Location in stream: 9307 Rewinding... Location in stream: 9307 Attempting fix... Location in stream: 9307 Rewinding... Location in stream: 9307 Actual result: -------------- Found in source at 9295 Location in stream: 15000 Rewinding... Location in stream: 15000 Attempting fix... Location in stream: 9307 Rewinding... Location in stream: 9307 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44607&edit=1
