Question

How can i convert an array like

Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [5] => F
)

to

Array
    (
        A
        B
        C
        D
        E
        F
    )

I tried using foreach key value and assigning value to new array , but even new array will be in 2D form

Answer 1

You should probably look into what 2D arrays are:

1D array:

Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [5] => F
)

1D associative array:

Array
(
    [foo] => A
    [bar] => B
    [moreFoo] => C
    [someElse] => D
)

2D array:

Array
(
    [0] => Array
    (
        [0] => A
        [1] => B
        [2] => C
        [3] => D
        [4] => E
        [5] => F
    )
    [1] => Array
    (
        [0] => A
        [1] => B
        [2] => C
        [3] => D
        [4] => E
        [5] => F
    )
    [2] => Array
    (
        [0] => A
        [1] => B
        [2] => C
        [3] => D
        [4] => E
        [5] => F
    )
)

2D associative array:

Array
(
    [foo] => Array
    (
        [foo] => A
        [bar] => B
        [moreFoo] => C
        [someElse] => D
    )
    [name] => Array
    (
        [foo] => A
        [bar] => B
        [moreFoo] => C
        [someElse] => D
    )
    [thirdElement] => Array
    (
        [foo] => A
        [bar] => B
        [moreFoo] => C
        [someElse] => D
    )
)
