note 123599 added to language.variables.variable

The feature of variable variable names is welcome, but it should be avoided when possible. Modern IDE software fails to interpret such variables correctly, regular find/replace also fails. It's a kind of magic :) This may really make it hard to refactor code. Imagine you want to rename variable $username to $userName and try to find all occurrences of $username in code by checking "$userName". You may easily omit: $a = 'username'; echo $$a; ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.142 (proxied: 2a02:a318:c33e:e880:dd4d:faf3:e459:177a) ---- Manual Page -- http://php.net/manual/en/language.variables.variable.php Edit -- https://master.php.net/note/edit/123599 Del: integrated -- https://master.php.net/note/delete/123599/integrated Del: useless -- https://master.php.net/note/delete/123599/useless Del: bad code -- https://master.php.net/note/delete/123599/bad+code Del: spam -- https://master.php.net/note/delete/123599/spam Del: non-english -- https://master.php.net/note/delete/123599/non-english Del: in docs -- https://master.php.net/note/delete/123599/in+docs Del: other reasons-- https://master.php.net/note/delete/123599 Reject -- https://master.php.net/note/reject/123599 Search -- https://master.php.net/manage/user-notes.php
