I have an array which is multidimensional for no reason
/* 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
)
)
)
I want to convert this array into this form
/*Now, I want to simply it down to this*/
Array (
[0] => basic
[1] => small
[2] => novice
[3] => professional
[4] => master
[5] => promo
[6] => newplan
)
Any idea how to do this?
