在php中将索引数组转换为多维关联/索引数组

Question

My array looks like this

Array
(
    [0] => A
    [1] => B
    [2] => C
)

Desired array

Array
(
    [0] => Array
        (
            [0] => A
        )

    [1] => Array
        (
            [0] => B
        )

    [2] => Array
        (
            [0] => C
        )
)

I have gone through these links but didn't able to figure out the solution being a newbie.

Convert associative array into indexed

convert indexed multidimensional array to associative multidimensional array

Answer 1

This is a blanket statement on how to get your desired array :

$desired_array = array(array("0"=>"A"), array("0"=>"B"), array("0"=>"C"));

However, dynamically, you could do the following :

//Assume $original_array = array("0"=>"A", "1"=>"B", "2"=>"C");

$desired_array = array(); // New Array
for($i = 0; $i < count($original_array); $i++){ // Loop over all elements in original array
array_push($desired_array, array("0"=>$original_array[$i])); // Place each valueable as an array in new desired array
}
