How do I sort the following array?

Question

I have this array:

  Array
(
[0] => Array
    (
        [id] => 6347
        [lat] => 18.520430
        [lng] => 73.856743
        [country_id] =         


        

Answer 1

Take a look at usort function.

Just define a function (in the manual as "cmp") for sorting and use it as callback:

function my_sorting_function($a, $b)
{
    return $a["avgRate"]>$b["avgrate"]?1:-1;
}

and then call it

usort($my_array_variable,"my_sorting_function");
