$arr = Array
(
[id] => Array
(
[0] => 5
[1] => 6
)
[company_id] => Array
(
[0] => 3
[1] => 3
)
）
生成如下格式：
$arr2 = Array （
[0] => Array
(
[id] => 5
[company_id] => 3
)
[1] => Array
(
[id] => 6
[company_id] => 3
)
）
语句为：
foreach($arr
as $k => $v) {
foreach($v as $k1 => $v1) {
$arr2[$k1][$k] = $v1;
}
}
注意用foreach时检查参数是否是数组
