PHP-排序多维数组

Question

I am trying to arrange my array (below) by [date], but to no avail as of yet :(

Needed to pad this out with some more text as apparently it's mostly code and stackoverflow doesn't like this :/

Array
(
    [0] => gapiReportEntry Object
        (
            [metrics:gapiReportEntry:private] => Array
                (
                    [uniquepageviews] => 0
                    [pageviews] => 0
                    [visits] => 0
                    [visitors] => 0
                )

            [dimensions:gapiReportEntry:private] => Array
                (
                    [date] => 20131009
                )

        )

    [1] => gapiReportEntry Object
        (
            [metrics:gapiReportEntry:private] => Array
                (
                    [uniquepageviews] => 1
                    [pageviews] => 1
                    [visits] => 1
                    [visitors] => 1
                )

            [dimensions:gapiReportEntry:private] => Array
                (
                    [date] => 20131026
                )

        )
)

Can anyone help me? Thanks,

You can use standard php usort function to do it :

$array = usort($array, function ($a, $b) use ($array){
    return strcmp($a -> dimensions -> date,  $b -> dimensions -> date);
}):

Notice I use a closure here (see http://php.net/manual/fr/function.usort.php ))

Considering the array is called $array, try this code:

$dates = array();
foreach($array as $v)
    $dates[] = $v['dimensions:gapiReportEntry:private'];

asort($dates);

$sorted_array = array();
foreach($dates as $k => $v)
    $sorted_array[$k] = $array[$k];

You will have the result in the $sorted_array variable.
