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
This is not a 2d array to start with. It is a 1d array... all arrays in PHP comprise key/value pairs. so
array('A','B')
is a 1d array with values A and B, to which keys are automatically assigned (0 and 1) as their offset position in that array.
A 2d array would be something like
array( array('A','B')
array('C','D')
)
to which keys are automatically assigned (0 and 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
)
)
Your question doesn't make sense... If you have that "flat" array, how are you gonna address, for example the 3rd element of it?
Also as @Shiplu mentioned in the comment, the array you use as an example is already a 1-d array, 2-d's array is in the form of
$array['level1']['level2'] = 'value';
All arrays in php have keys, whether you assign them or not when you create the array. The index starts at 0, so you would access A for example using 0, B using 1 etc.
If I correctly understand your question, you want to convert an unsorted indexed array something similar to:
array (
[2] => A,
[5] => B,
[8] => C,
["x"] => D,
["v"] => E,
[0] => F
);
to
array (
A,
B,
C,
D,
E,
F
);
If it is the case then use the array_values function.
$arr = array_values($arr);
implode('', $array)the array. Which you could still access with $string[0] => A, though.
