note 115732 added to function.ob-start

When creating a shortcode i've seen code which uses the callback function however its not always needed as this example demonstrates: <?php function wpsites_comment_form_shortcode() { ob_start(); comment_form(); $cform = ob_get_contents(); ob_end_clean(); return $cform; } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 183.89.139.70 ---- Manual Page -- http://php.net/manual/en/function.ob-start.php Edit -- https://master.php.net/note/edit/115732 Del: integrated -- https://master.php.net/note/delete/115732/integrated Del: useless -- https://master.php.net/note/delete/115732/useless Del: bad code -- https://master.php.net/note/delete/115732/bad+code Del: spam -- https://master.php.net/note/delete/115732/spam Del: non-english -- https://master.php.net/note/delete/115732/non-english Del: in docs -- https://master.php.net/note/delete/115732/in+docs Del: other reasons-- https://master.php.net/note/delete/115732 Reject -- https://master.php.net/note/reject/115732 Search -- https://master.php.net/manage/user-notes.php
