Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php clearstatcache(); Previous Comments: ------------------------------------------------------------------------ [2006-08-28 06:58:52] [EMAIL PROTECTED] The documentation is apparently wrong. ------------------------------------------------------------------------ [2006-08-28 03:16:30] rrlin923 at hotmail dot com Description: ------------ The manual said that "w" mode for fopen() will place the file pointer at the beginning of the file and truncate the file to zero length. But the file cannot be truncated using that "w" mode by fopen(). Reproduce code: --------------- <? $file = "t.log"; $add_content = "add this"; /* prepare the file to be truncated */ $fh = fopen($file, 'w'); $res = fwrite($fh, $add_content) or die("write file error"); fclose($fh); echo $file . " size : " . filesize($file) . "bytes. \n"; $sh = fopen($file, 'w'); fclose($sh); echo $file . " size : " . filesize($file) . "bytes. \n"; ?> Expected result: ---------------- t.log size : 8bytes. t.log size : 0bytes. Actual result: -------------- t.log size : 8bytes. t.log size : 8bytes. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38621&edit=1
