            [location] => blah blah
            [address] =>         


        

Answer 1

If you want to avoid the looping you can use the array_column function to achieve your target. For Example,

You want to sort below array with distance sort

$arr = array( 
  0 => array( 'lat' => 34, 'distance' => 332.08 ),
  1 => array( 'lat' => 34, 'distance' => 5 ),
  2 => array( 'lat' => 34, 'distance' => 34 )
);

Using below single line your array will be sort by distance

array_multisort( array_column( $arr, 'distance' ), SORT_ASC, SORT_NUMERIC, $arr );

Now, $arr contain with sorted array by distance
