    In case your keys are also dynamic you can try below code:

    $temp = [];
    foreach ($array as $item) {
        foreach ($item as $key => $itemValue) {
            $temp[$key][] = $itemValue;
        }
    }

print_r($temp);

    Hope it helps the arrray_column() solution is more efficient in case of not dynamic.

    You can group these and to do unique and sort at finish.

    
<?php


$data = [
    [
            "Contact Info" => 5
        ],
        [
            "Address Info" => 85
        ],
    [
            "Address Info" => 885
        ],
    [
            "Contact Info" => 592
        ],
    [
            "Address Info" => 85
        ],
    [
        "Address Info" => 8
        ],
    [
            "Contact Info" => 3
        ],
            [
            "Contact Info" => 3
        ],
    
    ];
$dumpData = ['Contact Info'=>array_unique(array_column($data,'Contact Info')),'Address Info'=> array_unique(array_column($data,'Address Info'))];
sort($dumpData['Contact Info']);
sort($dumpData['Address Info']);

echo'<pre>';

print_r($dumpData);
