note 125329 added to function.array-merge-recursive

An alternative solution where this function does not produce the desired output: Pass a custom recursive function to array_reduce(): For example (Using PHP 7 capabilities to create recursive anonymous function): <?php function array_merge_recursive(...$arrays): ?array { return array_reduce($arrays, new class { public function __invoke($carry, $item) { if (is_array($carry) && is_array($item) { return $this($carry, $item); } return $item ?: $carry; } } } ?> In this case truthy values will overwrite the value in the previous array. Of course this is presented as a simple example only, and is not a general solution. ---- Server IP: 45.112.84.4 Probable Submitter: 103.51.167.36 (proxied: 217.155.37.251) ---- Manual Page -- http://php.net/manual/en/function.array-merge-recursive.php Edit -- https://master.php.net/note/edit/125329 Del: integrated -- https://master.php.net/note/delete/125329/integrated Del: useless -- https://master.php.net/note/delete/125329/useless Del: bad code -- https://master.php.net/note/delete/125329/bad+code Del: spam -- https://master.php.net/note/delete/125329/spam Del: non-english -- https://master.php.net/note/delete/125329/non-english Del: in docs -- https://master.php.net/note/delete/125329/in+docs Del: other reasons-- https://master.php.net/note/delete/125329 Reject -- https://master.php.net/note/reject/125329 Search -- https://master.php.net/manage/user-notes.php
