note 116073 added to pdo.connections

The comment http://php.net/manual/en/pdo.connections.php#114822 makes a very valid point. When we use the suggested method of dropping the connection by doing: <?php $pdo = null; ?> The connection doesn't get dropped as described in the documentation. You may run into the issue when running too many unit tests (it's never too many, though), resulting in PostgreSQL hitting the connection limit after 150's test. The workaround is to use gc_collect_cycles() after unsetting the $pdo. <?php $pdo = null; gc_collect_cycles() ?> The relevant bug is reported here http://bugs.php.net/bug.php?id=68360, upvote if you care. ---- Server IP: 72.52.91.14 Probable Submitter: 62.106.104.22 ---- Manual Page -- http://php.net/manual/en/pdo.connections.php Edit -- https://master.php.net/note/edit/116073 Del: integrated -- https://master.php.net/note/delete/116073/integrated Del: useless -- https://master.php.net/note/delete/116073/useless Del: bad code -- https://master.php.net/note/delete/116073/bad+code Del: spam -- https://master.php.net/note/delete/116073/spam Del: non-english -- https://master.php.net/note/delete/116073/non-english Del: in docs -- https://master.php.net/note/delete/116073/in+docs Del: other reasons-- https://master.php.net/note/delete/116073 Reject -- https://master.php.net/note/reject/116073 Search -- https://master.php.net/manage/user-notes.php
