我有一个无缘无故多维的数组
/* This is how my array is currently */
Array
(
[0] => Array
(
[0] => Array
(
[plan] => basic
)
[1] => Array
(
[plan] => small
)
[2] => Array
(
[plan] => novice
)
[3] => Array
(
[plan] => professional
)
[4] => Array
(
[plan] => master
)
[5] => Array
(
[plan] => promo
)
[6] => Array
(
[plan] => newplan
)
)
)
我想把这个数组转换成这种形式
/*Now, I want to simply it down to this*/
Array (
[0] => basic
[1] => small
[2] => novice
[3] => professional
[4] => master
[5] => promo
[6] => newplan
)
知道如何做到这一点吗？
这一行就可以做到这一点：
$array = array_column($array, 'plan');
第一个参数是一个数组 |第二个参数是数组键。
