Sort the array elements based on the date values in the array

Question

I have an array like

Array ( [0] => Luke Karizo => Jul 18 2021 [1] => telse Elarazo => Aug 15 2021 [2] => Sarath S => Jul 08 2021 )

I am trying to reorder or sort the elements based on the date values in it. What I have tried is

function date_sort($a, $b) {
    return strtotime($a) - strtotime($b);
}
usort($main_Array, "date_sort");
print_r($main_Array);

I am expecting a result like

Array ( [0] => Sarath S => Jul 08 2021 [1] => Luke Karizo => Jul 18 2021 [2] => telse Elarazo => Aug 15 2021)

Is there any way I can sort this array based on the date values? Any help would be appreciated.

i am not sure about the array that you are giving, if you could rewrite it properly that would be nice,

but if it is a multidimensional array like i think it is, it should be like :

Array
(
[0] => Array
    (
        [name]     => Luke Karizo,
        [datetime] => Jul 18 2021
    )

[1] => Array
    (
        [name]     => Sarath S,
        [datetime] => Jul 08 2021
    )
...

and this should do the work :

function date_compare($a, $b)
{
    return strtotime($a['datetime']) - strtotime($b['datetime']);
}    
usort($array, 'date_compare');
print_r($array);

Tried this and not getting the result as expected. Please see below

Array (     [0] => Array         (             [name] => Luke Karizo             [birth_Day] => 1942/07/18         )      [1] => Array         (             [name] => Natelse Elarazo             [birth_Day] => 1947/08/15         )      [2] => Array         (             [name] => Sarath S             [birth_Day] => 1990/07/08         )  )
