#21120 [NEW]: fflush doesn`t work

From: rashid@php.net Operating system: win2k pro PHP version: 4.2.3 PHP Bug Type: Filesystem function related Bug description: fflush doesn`t work this is not the same as http://bugs.php.net/bug.php?id=19711 :) the following code on my platform displays: File size: 0, written: 2890 File size: 2890, written: 2890 as far as i know fflush should flush output to file at the moment of calling :] moving the line with flcose to the end of script causes that also the second display shows File size: 0, written: 2890 it looks for me that fflush doesn`t work and all flushing is done during file closing. tested it under linux also - both variants are done ok there: File size: 2890, written: 2890 File size: 2890, written: 2890 $str = ''; for($i = 0;$i < 1000;$i++) { $str .= $i; } $fp = fopen('test.txt', 'wb'); $written = fwrite($fp, $str); fflush($fp); clearstatcache(); $size = filesize('test.txt'); echo 'File size: '.$size.', written: '.$written.'<br>'; fclose($fp); clearstatcache(); $size = filesize('test.txt'); echo 'File size: '.$size.', written: '.$written.'<br>'; -- Edit bug report at http://bugs.php.net/?id=21120&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=21120&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=21120&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=21120&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=21120&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=21120&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=21120&r=support Expected behavior: http://bugs.php.net/fix.php?id=21120&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=21120&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=21120&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=21120&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=21120&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=21120&r=dst IIS Stability: http://bugs.php.net/fix.php?id=21120&r=isapi
