note 130272 added to function.array-column

I didn't see this explicitly mentioned in the documentation but if an array value is not an array (or an object with the correct functions for access) or the column_key doesn't exist then that value will simply not have a corresponding value in the output so array_column([[4,5,6], [7,8,9], 10], 0) will return [4,7]. It also means that the suggestion of array_combine(array_keys($array), array_column($array, 'column')); to preserve keys isn't safe unless you verify that nothing will be excluded by the array_column call. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.84.18 (proxied: 76.132.2.185) ---- Manual Page -- https://php.net/manual/en/function.array-column.php Edit -- https://main.php.net/note/edit/130272 Del: integrated -- https://main.php.net/note/delete/130272/integrated Del: useless -- https://main.php.net/note/delete/130272/useless Del: bad code -- https://main.php.net/note/delete/130272/bad+code Del: spam -- https://main.php.net/note/delete/130272/spam Del: non-english -- https://main.php.net/note/delete/130272/non-english Del: in docs -- https://main.php.net/note/delete/130272/in+docs Del: other reasons-- https://main.php.net/note/delete/130272 Reject -- https://main.php.net/note/reject/130272 Search -- https://main.php.net/manage/user-notes.php
