note 63301 added to function.ob-start

ive just tried the following code, and it wont work! 1 <?php 2 ob_start(""); 3 echo "hi"; 4 setcookie("bob", 1, time()+9999999, "/"); 5 ob_end_flush(); 6 ?> PHP Warning: Cannot modify header information - headers already sent by (output started at C:\\Program Files\\Apache Group\\Apache2\\htdocs\\obtest.php:3) in C:\\Program Files\\Apache Group\\Apache2\\htdocs\\obtest.php on line 4 PHP Notice: ob_end_flush(): failed to delete and flush buffer. No buffer to delete or flush. in C:\\Program Files\\Apache Group\\Apache2\\htdocs\\obtest.php on line 5 i see that i have output_buffering = 0 in my phpinfo page, as it is commented out in my configuration. i dont want to have output buffering by default on all files, but it seems that the only time output buffering ACTUALLY does its job and sends headers first is when i turn this directive on. is this a bug in version 5.1.2 or is there something else that is to blame? ---- Server IP: 66.207.199.35 Probable Submitter: 198.53.253.173 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.ob-start.php Edit -- http://master.php.net/note/edit/63301 Del: integrated -- http://master.php.net/note/delete/63301/integrated Del: useless -- http://master.php.net/note/delete/63301/useless Del: bad code -- http://master.php.net/note/delete/63301/bad+code Del: spam -- http://master.php.net/note/delete/63301/spam Del: non-english -- http://master.php.net/note/delete/63301/non-english Del: in docs -- http://master.php.net/note/delete/63301/in+docs Del: other reasons-- http://master.php.net/note/delete/63301 Reject -- http://master.php.net/note/reject/63301 Search -- http://master.php.net/manage/user-notes.php
