PHP数组重新排列为多维
我有一个这样的数组结构，想把它重新安排到下面的那个。有没有更快/更简单的解决方案的建议？我已经添加了日期。谢谢！：） 输入：PHP数组重新排列为多维,php,arrays,multidimensional-array,Php,Arrays,Multidimensional Array,我有一个这样的数组结构，想把它重新安排到下面的那个。有没有更快/更简单的解决方案的建议？我已经添加了日期。谢谢！：） 输入： Array ( [0] => Array ( [user_id] => 255 [display_name] => Mark [company_name] => Company_A ) [1] => Array

我不知道你的工作时间是从哪里来的，所以我把它删掉了
$i = 0;
foreach($vals as $keys => $arrays) {
if(!isset($new[$arrays['company_name']]))
$i = 0;
$new[$arrays['company_name']]['employees'][$i]['display_name'] = $arrays['display_name'];
$new[$arrays['company_name']]['employees'][$i]['user_id'] = $arrays['user_id'];
$i++;
}

我创建了一个函数，它的作用与@Rasclatt给出的答案相同
function groupByKeyValue($array, $oldKeyName, $newKeyName){
$newArray = array();
foreach($array as $key=>$value){
if(isset($newArray[$value[$oldKeyName]][$newKeyName])){
$newArray[$value[$oldKeyName]][$newKeyName][] = array('user_id'=> $value['user_id'], 'display_name' => $value['display_name']);
}else{
$newArray[$value[$oldKeyName]] = array($newKeyName => array(array('user_id'=> $value['user_id'], 'display_name' => $value['display_name'])));
}
}
return $newArray;
}
//usage
$newArray = groupByKeyValue($array, 'company_name', 'employees');
您可以添加第三个参数来发送数组值的键，该数组值需要在“employees”的新数组中使用。请检查此链接以了解该功能的工作情况请发布您的尝试。你尝试了什么，从哪里得到的？谢谢你做得很好。其他答案也同样有效。我刚刚加上了你忘了的“公司总小时”键。再次感谢：）
