php数组合并

有三个一维数组，
Array ( [0] => 12312 [1] => 2321 [2] => 12321 )
Array ( [0] => 133 [1] => 444 [2] => 888 )
Array ( [0] => qqqqqqq [1] => wqwq [2] => wqe )

合并成
array( [orderno] => 12312 [deliverysn] => 133 [deliverycorpname] => qqqqqqq)

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

不知道题主是不是这个意思，效果如下

//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 

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