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)

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

不知道题主是不是这个意思，效果如下

<code class="php">//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);</code>

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