[英]How to merge array within array to single array
I am trying to merge the associative array to single array but no success . 我试图将关联数组合并到单个数组,但没有成功。
Array
(
[0] => Array
(
[313] => 9513
[361] => 2280
[68] => 9513
[363] => 1591
[314] => 1610
[355] => 1908
[357] => 1445
[389] => 290
[358] => 203
[388] => 157
[360] => 144
[362] => 105
[383] => 28
)
[1] => Array
(
[385] => 5619
[4] => 25090
[45] => 25090
[321] => 6041
[323] => 3208
[324] => 2686
[317] => 2474
[327] => 1868
[386] => 1680
[310] => 1698
[312] => 539
[320] => 406
[390] => 369
[326] => 331
[315] => 285
[325] => 219
[356] => 226
[318] => 213
[311] => 138
[319] => 110
[382] => 61
)
[2] => Array
(
[4] => 54098
[5] => 54098
[8] => 30669
[18] => 4880
[74] => 3457
[17] => 2702
[21] => 2217
[14] => 2216
[73] => 2109
[7] => 10085
[66] => 1969
[20] => 1481
[13] => 1234
[64] => 1180
[11] => 1097
[75] => 727
[15] => 592
[67] => 767
[10] => 457
[391] => 352
[387] => 356
)
)
The expected output is :- 预期的输出是:-

If you don't know the number of elements, the obvious way would be to do it in a loop: 如果您不知道元素的数量,那么显而易见的方法是循环执行:
$newArray = array();
foreach ($multiarray as $array){
$newArray = array_merge($newArray,array_values($array));
}
// $newArray contains your flattened array.
Note however that you cannot have multiple array elements with the same key - it's not possible. 但是请注意,不能有多个具有相同键的数组元素-这是不可能的。 I've set it up to discard the array keys and just keep the values - if you want to keep the keys (but bear in mind that a 'newer' key will override an older key, then remove the call to array_values()
我已将其设置为丢弃数组键并仅保留值-如果您想保留键(但请记住,“更新”键将覆盖旧键,然后删除对array_values()的调用
