PHP多维数组过滤器

I found this manual page but I'm still not sure what to use. I have this array:

Array (
[unique_key] => 7439db65fe2856a636e3c6d9841b51ed
[thwepof_options] => Array (
[order_date] => Array (
[name] => order_date
[value] => 29-01-2018, monday
[label] => Order date [options] => ) )

So first I just foreach every [thwepof_options] => value, sorted and made them unique (because I need that once):

<?php foreach (WC()->cart->get_cart() as $order_dates => $order_date): ?>
    <?php $options = $order_date['thwepof_options']; ?>
        <?php foreach($options as $option => $dates): ?>
            <?php array_push($myarray, $dates['value']) ?>
        <?php endforeach; ?>
<?php endforeach; ?>
<?php sort($myarray); ?>
<?php $unique = array_unique($myarray); ?>
//later in that code
<?php foreach($unique as $dates => $date_value): ?>
            <tr>
                <h1><?php echo $date_value ?></h1></td>
            </tr>
<?php endforeach; ?>

With WC()->cart->get_cart() method I can get the whole array. I need some kind of filter which removes every value from that array where $date_value isn't equal with the [thwepof_options] => [value] (or show only those where is equal) to make an another foreach loop.

    Try this:

    array_filter(
            $unique, // Array to filter
            function($elem){ // Closure performing filtration
                // When this returns FALSE, items will be removed
                return $elem['order_date']['value'] == $date_value;
            }
        );
    

    It is not entirely clear where you are sourcing all of your values because not all code is provided, but I hope this successfully demonstrates an easy way to filter your array.
