note 99363 added to language.types.array

It is true that "array assignment always involves value copying", but the copy is a "lazy copy". This means that the data of the two variables occupy the same memory as long as no array element changes. E.g., if you have to pass an array to a function that only needs to read it, there is no advantage at all in passing it by reference. ---- Server IP: 69.147.83.197 Probable Submitter: 151.8.106.201 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- https://master.php.net/note/edit/99363 Del: integrated -- https://master.php.net/note/delete/99363/integrated Del: useless -- https://master.php.net/note/delete/99363/useless Del: bad code -- https://master.php.net/note/delete/99363/bad+code Del: spam -- https://master.php.net/note/delete/99363/spam Del: non-english -- https://master.php.net/note/delete/99363/non-english Del: in docs -- https://master.php.net/note/delete/99363/in+docs Del: other reasons-- https://master.php.net/note/delete/99363 Reject -- https://master.php.net/note/reject/99363 Search -- https://master.php.net/manage/user-notes.php
