note 119939 added to function.timezone-name-from-abbr

In some cases, timezone_name_from_abbr() may return a "historical" (i.e. deprecated) timezone identifier rather than the current standard one for a given location. For example: <?php echo timezone_name_from_abbr('EASST'); // prints "Chile/EasterIsland" instead of "Pacific/Easter" ?> This means that the returned timezone identifier is not guaranteed to be in the results of timezone_identifiers_list() unless you include the "backwards compatible" timezones. <?php var_dump(in_array(timezone_name_from_abbr('EASST'), timezone_identifiers_list())); // (bool)false var_dump(in_array(timezone_name_from_abbr('EASST'), timezone_identifiers_list(DateTimeZone::ALL_WITH_BC))); // (bool)true ?> ---- Server IP: 72.52.91.14 Probable Submitter: 198.48.161.227 ---- Manual Page -- http://php.net/manual/en/function.timezone-name-from-abbr.php Edit -- https://master.php.net/note/edit/119939 Del: integrated -- https://master.php.net/note/delete/119939/integrated Del: useless -- https://master.php.net/note/delete/119939/useless Del: bad code -- https://master.php.net/note/delete/119939/bad+code Del: spam -- https://master.php.net/note/delete/119939/spam Del: non-english -- https://master.php.net/note/delete/119939/non-english Del: in docs -- https://master.php.net/note/delete/119939/in+docs Del: other reasons-- https://master.php.net/note/delete/119939 Reject -- https://master.php.net/note/reject/119939 Search -- https://master.php.net/manage/user-notes.php
