在其他数组中，将数组值添加到每个子数组的开头
在其他数组中，将数组值添加到每个子数组的开头
我有两个数组，$array1和$array2，现在我想从$array2中取出值，并将每个元素放在$array1的每个子数组的开头。
第一个数组：
$array1 = Array (
[0] => Array (
[0] => 2
[1] => 6
[2] => 15
[3] => 6
)
[1] => Array (
[0] => 5
[1] => 8
[2] => 6
[3] => 12
)
[2] => Array (
[0] => 2
[1] => 5
[2] => 5
[3] => 5
)
)
第二个数组：
$array2 = Array (
[0] => Outlook
[1] => Temp
[2] => Humidity
)
期望的输出（修改/新的值用粗体表示）：
$array1 = Array (
[0] => Array (
[0] => 'Outlook'
[1] => 2
[2] => 6
[3] => 15
[4] => 6
)
[1] => Array (
[0] => 'Temp'
[1] => 5
[2] => 8
[3] => 6
[4] => 12
)
[2] => Array (
[0] => 'Humidity'
[1] => 2
[2] => 5
[3] => 5
[4] => 5
)
)
