我想將條目匯總到一個數(shù)組（動態(tài)數(shù)組，從數(shù)據(jù)庫中獲取的數(shù)據(jù)）并返回每個條目的總和。多維數(shù)組具有以下形狀：<?php$sample = array("term_1_mid" => array("English" => 56,"Mathematics" => 34,"Creative Arts" => 87),"term_1_end" => array("English" => 67,"Mathematics" => 59,"Creative Arts" => 95));我想要做的是將“term_1_mid”中的樣本數(shù)組的值添加到“term_1_end”中相同樣本數(shù)組的值中......所以得到的求和輸出應(yīng)該是這樣的：<?php$result = array("English" => 123, // 56 + 67 from above"Mathematics" => 93, // 34 + 59"Creative Arts" => 182 // 87 + 95);有什么辦法可以做到這一點(diǎn)？我嘗試了以下代碼，但它似乎不起作用：<?php$final_score = [];array_push($final_score, array_map(function($arr, $arr1) {return $arr + $arr1;}, $sample["term_1_mid"], $sample["term_1_end"]));print_r($final_score);
