note 117528 added to reserved.variables.server

I've used the SplPriorityQueue to determine an HTTP client's preferred MIME types that are in $_SERVER['HTTP_ACCEPT']. <?php $queue = new \SplPriorityQueue(); foreach (preg_split('#,\s*#', $_SERVER['HTTP_ACCEPT']) as $accept) { $split = preg_split('#;\s*q=#', $accept, 2); $queue->insert($split[0], isset($split[1]) ? (float)$split[1] : 1.0); } foreach ($queue as $mime) { echo $mime, PHP_EOL; } ?> My browser sends: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 And this script outputs: text/html application/xhtml+xml application/xml */* A better example: Accept: text/html, application/xml,text/css;q=0.4,text/plain; q=0.9, application/json;q=0.8 And this script outputs: text/html application/xml text/plain application/json text/css ---- Server IP: 72.52.91.14 Probable Submitter: 108.3.219.161 ---- Manual Page -- http://php.net/manual/en/reserved.variables.server.php Edit -- https://master.php.net/note/edit/117528 Del: integrated -- https://master.php.net/note/delete/117528/integrated Del: useless -- https://master.php.net/note/delete/117528/useless Del: bad code -- https://master.php.net/note/delete/117528/bad+code Del: spam -- https://master.php.net/note/delete/117528/spam Del: non-english -- https://master.php.net/note/delete/117528/non-english Del: in docs -- https://master.php.net/note/delete/117528/in+docs Del: other reasons-- https://master.php.net/note/delete/117528 Reject -- https://master.php.net/note/reject/117528 Search -- https://master.php.net/manage/user-notes.php
