note 126810 added to function.array-sum

If you want to calculate the sum in multi-dimensional arrays: <?php function array_multisum(array $arr): float { $sum = array_sum($arr); foreach($arr as $child) { $sum += is_array($child) ? array_multisum($child) : 0; } return $sum; } ?> Example: <?php $data = [ 'a' => 5, 'b' => [ 'c' => 7, 'd' => 3 ], 'e' => 4, 'f' => [ 'g' => 6, 'h' => [ 'i' => 1, 'j' => 2 ] ] ]; echo array_multisum($data); //output: 28 ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 213.94.44.213) ---- Manual Page -- https://php.net/manual/en/function.array-sum.php Edit -- https://main.php.net/note/edit/126810 Del: integrated -- https://main.php.net/note/delete/126810/integrated Del: useless -- https://main.php.net/note/delete/126810/useless Del: bad code -- https://main.php.net/note/delete/126810/bad+code Del: spam -- https://main.php.net/note/delete/126810/spam Del: non-english -- https://main.php.net/note/delete/126810/non-english Del: in docs -- https://main.php.net/note/delete/126810/in+docs Del: other reasons-- https://main.php.net/note/delete/126810 Reject -- https://main.php.net/note/reject/126810 Search -- https://main.php.net/manage/user-notes.php
