note 123566 added to function.array-merge

Something I ran across that may be useful to some. If one of the parameters in the merge is NOT an array you won't receive a notice that type is incorrect. Instead the merged array will nullify. <?php $first = 'foo'; $second = ['bar', 'again']; $merged = array_merge($first, $second); var_dump($merged); // will display null ?> ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.35 (proxied: 96.71.17.137) ---- Manual Page -- http://php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/123566 Del: integrated -- https://master.php.net/note/delete/123566/integrated Del: useless -- https://master.php.net/note/delete/123566/useless Del: bad code -- https://master.php.net/note/delete/123566/bad+code Del: spam -- https://master.php.net/note/delete/123566/spam Del: non-english -- https://master.php.net/note/delete/123566/non-english Del: in docs -- https://master.php.net/note/delete/123566/in+docs Del: other reasons-- https://master.php.net/note/delete/123566 Reject -- https://master.php.net/note/reject/123566 Search -- https://master.php.net/manage/user-notes.php
