Sorting multidimensional array, upper case being sorted before lowercase

Question

Using the below for sorting a multidimensional array by screen name:

$sortArray = array();

foreach($members as $member){
    foreach($member as $key=>$value)         


        

Answer 1

uasort() should work for you

'Greg'),
    array('screen_name'=>'Allen'),
    array('screen_name'=>'dan'),
    array('screen_name'=>'Brenda'),
);

// uasort() like a boss!
uasort($members, 'sort_by_screen_name');

print_r($members);

Output

Array
(
    [1] => Array
        (
            [screen_name] => Allen
        )

    [3] => Array
        (
            [screen_name] => Brenda
        )

    [2] => Array
        (
            [screen_name] => dan
        )

    [0] => Array
        (
            [screen_name] => Greg
        )

)

Note: the original array keys are preserved using this method. If you'd like the keys to be rewritten, you can simply use usort().
