note 103090 added to datetime.installation

The statement "the DateTime class (and related functions) are enabled by default since PHP 5.2.0" is not entirely true. For example, the DateInterval class did not become available until 5.3.0 and since the function DateTime::diff returns a DateInterval object, this function is not available in 5.2.0. ---- Server IP: 69.147.83.197 Probable Submitter: 216.252.78.91 ---- Manual Page -- http://www.php.net/manual/en/datetime.installation.php Edit -- https://master.php.net/note/edit/103090 Del: integrated -- https://master.php.net/note/delete/103090/integrated Del: useless -- https://master.php.net/note/delete/103090/useless Del: bad code -- https://master.php.net/note/delete/103090/bad+code Del: spam -- https://master.php.net/note/delete/103090/spam Del: non-english -- https://master.php.net/note/delete/103090/non-english Del: in docs -- https://master.php.net/note/delete/103090/in+docs Del: other reasons-- https://master.php.net/note/delete/103090 Reject -- https://master.php.net/note/reject/103090 Search -- https://master.php.net/manage/user-notes.php
