php - Sort array by keys numeric first than ascending by string -


i have array:

array(1,'test','jonathan')

and id end with:

array(1,'jonathan','test')

how accomplish using php?

one possible approach (demo):

$arr = array(10,'foo', 'abc', 5, 3.2, 'test','jonathan'); usort($arr, function($a, $b) {   if (is_int($a) || is_float($a)) {     if (is_int($b) || is_float($b)) {       return $a - $b;      }     else        return -1;   }   elseif (is_int($b) || is_float($b)) {     return 1;   }   else {     return strcmp($a, $b);   } }); print_r($arr);

output:

array (     [0] => 3.2     [1] => 5     [2] => 10     [3] => abc     [4] => foo     [5] => jonathan     [6] => test )
