    php codehaven

    This is an array that looks for the first array and in that array has an element called ‘name’

    1
    2
    3
    4
    5
     
    usort($results, function($a, $b) {
            return strcasecmp($a[0]['name'], $b[0]['name']);
        });
     

    For a simpler version (notice the array number [0] is missing now)

    1
    2
    3
    4
    5
    6
     
    usort($data, function($a, $b) {
            return strcasecmp($a['name'], $b['name']);
        });
        }
