note 102192 added to datetime.sub

Note that the sub() and add() methods will modify the value of the object you're calling the method on! This is very untypical for a method that returns a value of its own type. You could misunderstand it that the method would return a new instance with the modified value, but in fact it modifies itself! This is undocumented here. (Only a side note on procedural style mentions it, but it obviously does not apply to object oriented style.) ---- Server IP: 217.160.235.204 Probable Submitter: 83.171.172.168 ---- Manual Page -- http://www.php.net/manual/en/datetime.sub.php Edit -- https://master.php.net/note/edit/102192 Del: integrated -- https://master.php.net/note/delete/102192/integrated Del: useless -- https://master.php.net/note/delete/102192/useless Del: bad code -- https://master.php.net/note/delete/102192/bad+code Del: spam -- https://master.php.net/note/delete/102192/spam Del: non-english -- https://master.php.net/note/delete/102192/non-english Del: in docs -- https://master.php.net/note/delete/102192/in+docs Del: other reasons-- https://master.php.net/note/delete/102192 Reject -- https://master.php.net/note/reject/102192 Search -- https://master.php.net/manage/user-notes.php
