Convert multidimentional array to a simple array

Question

When print_r($my_array);

Array
(
    [0] => Array
        (
            [value] => num1
            [label] => 
        )

    [1] => Array
        (
            [value] => num2
            [label] => 
        )

    [2] => Array
        (
            [value] => num3
            [label] => 
        )

)

Now I wonder how to create a new array variable to hold only 1 level with the following structure. e.g:

if print_r($new_array), it will show:

Array
(
    [0] => num1

    [1] => num2

    [2] => num3

)

what you have tried show your code?

Try foreach() and store value in new array

foreach($arr as $v) {
  $newarr[] = $v['value']; 
}
print_r($newarr);

Try with foreach of $my_array and assign value to $new_array variable like

$new_array = array();
foreach($my_array as $array){
  $new_array[] = $array['value'];
}
print_r($new_array);

Loop thru the array as follows and push the desired elements into a new array.

$new_array = array();

for($i=0;$i<count($my_array);$i++) {
    array_push($new_array, $my_array[$i]['value']);
}

print_r($new_array);

foreach ($my_array as $key => $value) {
    $new_array[] = $value['value'];
}
