PHP Array Merging

There are three one-dimensional arrays,
Array ( [0] => 12312 [1] => 2321 [2] => 12321 )
Array ( [0] => 133 [1] => 444 [2] => 888 )
Array ( [0] => qqqqqqq [1] => wqwq [2] => wqe )

Merged into
array( [orderno] => 12312 [deliverysn] => 133 [deliverycorpname] => qqqqqqq)

array( [orderno] => 2321 [deliverysn] => 444 [deliverycorpname] => wqwq )  一次类推怎么做

Do not know the main question is not the meaning, the effect is as follows

//首先要确定这3个数组是关联数组和所包含的元素个数都是一样的$arr_orderno = [12321,321,321];$arr_deliverysn = [7,8,9];$arr_deliverycorpname = ['asd','qwe','zxc'];$arr_merge= [];for($i = 0; $i < count($arr_orderno); $i++){  $arr_merge[$i] = [$arr_orderno[$i], $arr_deliverysn[$i], $arr_deliverycorpname[$i]];}$arr_key = ['orderno', 'deliverysn', 'deliverycorpname'];$arr = [];foreach ($arr_merge as $value) {  $arr[] = array_combine($arr_key, $value);}print_r($arr);

foreach($arr_a as $k=>$v){    $arr_{$k}['orderno'] = $v;    $arr_{$k}['deliverysn'] = $arr_b[$k];    $arr_{$k}['deliverycorpname'] = $arr_c[$k];}
