I also used this

foreach($response as $key2=>$weather)
        {
            //echo "<pre>"; print_r($weather);
            if($weather['level']==3)
            {
                $date=$weather['attributes']['DATEHRGMT'];
                $response2[$date]=$weather['attributes'];
            }   

        }
        echo "<pre>"; print_r($response2);

Update

Answer 1

This should work for you:

Just explode() your key and use the date as index, like this:

<?php

    $result = [];   

    foreach($arr as $k => $v)
        $result[explode(" ", $k)[0]][] = $v;

    print_r($result);

?>
