note 97966 added to language.variables.basics

I have not tested this snippet, but I doubt it is more efficient than using a temporary buffer through a third variable. To be simple and powerful, the PHP language provides you an high level of abstraction. In the low level of the PHP interpreter - into the practice -, this buffer is used since a third "block" of memory must be allocated to perform this permutation. ---- Server IP: 69.147.83.197 Probable Submitter: 82.244.57.183 ---- Manual Page -- http://www.php.net/manual/en/language.variables.basics.php Edit -- https://master.php.net/note/edit/97966 Del: integrated -- https://master.php.net/note/delete/97966/integrated Del: useless -- https://master.php.net/note/delete/97966/useless Del: bad code -- https://master.php.net/note/delete/97966/bad+code Del: spam -- https://master.php.net/note/delete/97966/spam Del: non-english -- https://master.php.net/note/delete/97966/non-english Del: in docs -- https://master.php.net/note/delete/97966/in+docs Del: other reasons-- https://master.php.net/note/delete/97966 Reject -- https://master.php.net/note/reject/97966 Search -- https://master.php.net/manage/user-notes.php
