note 90067 added to datetimezone.listabbreviations

Note that the dst field is of boolean type, so if you are doing an identity comparison, you need to test for true or false, not 0 or 1. For example: <?php $timezone_abbreviations = DateTimeZone::listAbbreviations(); foreach ($timezone_abbreviations["est"] as $tz) { echo $tz['timezone_id']; // if ($tz['dst'] === 1) will always evaluate to false if ($tz['dst'] === true) { echo " (DST observed)<br />\n"; } // Could use else here, but for illustration... if ($tz['dst'] === false) { echo " (DST not observed)<br />\n"; } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 74.160.32.242 ---- Manual Page -- http://www.php.net/manual/en/datetimezone.listabbreviations.php Edit -- https://master.php.net/note/edit/90067 Del: integrated -- https://master.php.net/note/delete/90067/integrated Del: useless -- https://master.php.net/note/delete/90067/useless Del: bad code -- https://master.php.net/note/delete/90067/bad+code Del: spam -- https://master.php.net/note/delete/90067/spam Del: non-english -- https://master.php.net/note/delete/90067/non-english Del: in docs -- https://master.php.net/note/delete/90067/in+docs Del: other reasons-- https://master.php.net/note/delete/90067 Reject -- https://master.php.net/note/reject/90067 Search -- https://master.php.net/manage/user-notes.php
