I have an array like :
Array
(
[2] => 2,6
[3] => 1
[4] => 14
[5] => 10
[6] => 8
)
I want to explode each element of an array and return a new array using array_map, so that I can avoid using loop, and creating extra function to call back.
O/p should be like :
Array
(
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 1
)
[4] => Array
(
[0] => 14
)
[5] => Array
(
[0] => 10
)
[6] => Array
(
[0] => 8
)
)
You can use
$result = array_map(function($val) {
return explode(',', $val);
}, $input);
Which will result in
Array
(
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 1
)
[4] => Array
(
[0] => 14
)
[5] => Array
(
[0] => 10
)
[6] => Array
(
[0] => 8
)
)
This will work on PHP >= 5.3 with support for anonymous functions.
