我有这样构建的数组
array (size=2)
0 =>
array (size=12)
'id_objects' => string '2876' (length=4)
'room_val' => string '1882840,1882841,1882842' (length=23)
'date_from' => string '2022-06-22' (length=10)
'date_to' => string '2022-06-22' (length=10)
1 =>
array (size=12)
'id_objects' => string '2876' (length=4)
'room_val' => string '3198723,3198724,3198726' (length=23)
'date_from' => string '2022-06-22' (length=10)
'date_to' => string '2022-06-22' (length=10)
我需要实现的是，爆炸'room_val'但保持其余数据相同，它需要看起来像这样
array (size=2)
0 =>
array (size=12)
'id_objects' => string '2876' (length=4)
'room_val' => string '1882840' (length=23)
'date_from' => string '2022-06-22' (length=10)
'date_to' => string '2022-06-22' (length=10)
1 =>
array (size=12)
'id_objects' => string '2876' (length=4)
'room_val' => string '1882841' (length=23)
'date_from' => string '2022-06-22' (length=10)
'date_to' => string '2022-06-22' (length=10)
..... rest of array
可能吗？
您需要解析数组数组并创建一个与您要查找的内容匹配的新数组。
类似于：
$myNewArray = []; foreach ($arrays as $array) { $room_vals = $array['room_val']; foreach ($room_vals as $room_val) { $newSubArray = $array; $newSubArray['room_val'] = $room_val; $myNewArray[] = $newSubArray; } }
