note 123926 added to function.array-shift

Using this code: $value = array_shift( a_function_that_returns_array() ); May result in a memory leak, as of PHP 7.3.5 (cli) (built: Apr 30 2019 21:05:09), while this one does not: $value = a_function_that_returns_array()[ 0 ]; It seems that this is not a bug and does generate a warning about passing values by reference. ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.195 (proxied: 5.248.205.243) ---- Manual Page -- http://php.net/manual/en/function.array-shift.php Edit -- https://master.php.net/note/edit/123926 Del: integrated -- https://master.php.net/note/delete/123926/integrated Del: useless -- https://master.php.net/note/delete/123926/useless Del: bad code -- https://master.php.net/note/delete/123926/bad+code Del: spam -- https://master.php.net/note/delete/123926/spam Del: non-english -- https://master.php.net/note/delete/123926/non-english Del: in docs -- https://master.php.net/note/delete/123926/in+docs Del: other reasons-- https://master.php.net/note/delete/123926 Reject -- https://master.php.net/note/reject/123926 Search -- https://master.php.net/manage/user-notes.php
