Php 将多维数组转换为另一个具有不同结构的多维数组
我在操作复杂数组时遇到了一些问题，如下所示：Php 将多维数组转换为另一个具有不同结构的多维数组,php,multidimensional-array,Php,Multidimensional Array,我在操作复杂数组时遇到了一些问题，如下所示： Array ( [0] => Array ( [checklist_position] => 8 [checklist_id] => 2 [question_id] => 11 [section] => 1 [sum_a] => 332611 [su

谢谢大家! 在数组的键中使用节号可能会少一些麻烦，例如（问题的第一个数组是$array1）：
还没有签出，但应该可以。Patroklo的解决方案简化了：
$result = array();
foreach($array1 as $data){
$section = $data['section'];
$result[$section]['section'] = $section;
$result[$section]['questions'][] = $data;
}
$result = array_values($result); // to re order
$array1是包含当前数据的数组，$result是您所期望的从循环原始数组开始，然后创建一个新数组。那么模式是什么呢？分割阵列碎片（每个2个阵列）并用不同的结构创建新阵列？@safarov，是的，我想用我在上面发布的结构创建一个新阵列。我想你缺少了一些括号。我确实得到了一些输出，但它并没有达到预期的效果。哦，你是说像$array1=$original_数组[0]？不，$array1=$original_数组；你只需要循环它，唯一的区别是在最后的数组中，而不是像->0，1，2，3这样的键。。。他们会说：1，2谢谢你，萨弗拉兹先生。输出与预期一致。还有一个问题。$result可以从0开始吗？现在它从1开始-再次检查答案-我编辑了它。当做
