note 93526 added to function.system

This might be a bug, but be aware that the system function, at least on PHP 5.2 on Linux, disrupts the output buffering process: Consider something along the lines of: <?php ob_start(); system('pwd'); header("location: http://news.bbc.co.uk"); ob_end_clean(); ?> This will not redirect to the bbc site as it seems an (invisible) output has already been written even though it was supposed to be captured. Consider using another function like exec() instead as a workaround as replacing system('pwd') with echo exec('pwd') will work as expected. ---- Server IP: 87.124.86.47 Probable Submitter: 188.220.60.237 (proxied: 188.220.60.237) ---- Manual Page -- http://www.php.net/manual/en/function.system.php Edit -- https://master.php.net/note/edit/93526 Del: integrated -- https://master.php.net/note/delete/93526/integrated Del: useless -- https://master.php.net/note/delete/93526/useless Del: bad code -- https://master.php.net/note/delete/93526/bad+code Del: spam -- https://master.php.net/note/delete/93526/spam Del: non-english -- https://master.php.net/note/delete/93526/non-english Del: in docs -- https://master.php.net/note/delete/93526/in+docs Del: other reasons-- https://master.php.net/note/delete/93526 Reject -- https://master.php.net/note/reject/93526 Search -- https://master.php.net/manage/user-notes.php
