PHP filter Массив после / во время использования для указанной c даты (RSS-канала)

Question

У меня есть небольшой скрипт (найден в сети), который собирает RSS-поток (ы) в массив, сортирует массив и затем отображает то, что вы хотите. Теперь я хотел бы иметь возможность отображать только элементы из ленты с указанной c датой (только сегодня). Может ли кто-нибудь помочь с фильтрацией отсортированного массива?

   <?php
    //Feed URLs
    $feeds = array(
        "https://www.abda.de/?type=1102",
        "https://www.abda.de/?type=1100",
    );

    //Read each feed's items
    $entries = array();
    foreach($feeds as $feed) {
        $xml = simplexml_load_file($feed);
        $entries = array_merge($entries, $xml->xpath("//item"));
    }

    //Sort feed entries by pubDate

    usort($entries, function ($feed1, $feed2) {
        return strtotime($feed2->pubDate) - strtotime($feed1->pubDate);
    });

    function showrssitem($i) {
        global $entries;
        $backgroundbutton = 'd3d3d3';
        switch ($entries[$i]->category) {
            case "Chargenrückrufe" :
                $backgroundbutton = 'ff9933';       /* orange */
                break;
            case "Rückrufe" :
                $backgroundbutton = 'ff9933';       /* orange */
                break;
            case "Informationen der Institutionen und Behörden" : 
                $backgroundbutton = 'ff3300';       /* red */

        $strippedentry1 = str_replace ("Online-Nachricht: ","", $entries[$i]->title); 
        $strippedentry2 = str_replace ("Informationen der Institutionen und Behörden: ","", $strippedentry1); 
        $strippedentry3 = str_replace ("Informationen der Hersteller: ","", $strippedentry2); 
        echo '<a style="text-decoration: none;" target="_blank" href="' . $entries[$i]->link . '"><button style="background-color: #' . $backgroundbutton . '; margin-bottom: 10px; width: 100%; height:75px; display: block; border-radius: 10px;">' . $entries[$i]->category . '</button></a>';
        echo mb_strimwidth($strippedentry3,0,100,"...") . "<br>";
        echo "<i>[" . strftime('%d/%m/%Y', strtotime($entries[$i]->pubDate)) . "]</i><br>";

Теперь у меня работает следующее решение. Если у вас есть предложения по более чистому способу, не стесняйтесь комментировать;)

   <?php
    //Feed URLs
    $feeds = array(
        "https://www.abda.de/?type=1102",
        "https://www.abda.de/?type=1100",
    );

    //Read each feed's items
    $entries = array();
    foreach($feeds as $feed) {
        $xml = simplexml_load_file($feed);
        $entries = array_merge($entries, ($xml->xpath("//item")));
    }

    //Sort feed entries by pubDate

    usort($entries, function ($feed1, $feed2) {
        return strtotime($feed2->pubDate) - strtotime($feed1->pubDate);
    });

    //Find latest date in array         $max = max(array_map('strtotime', $arr));
    $highestdate_entries = date('d-m-Y', max(array_map('strtotime', $entries)));    /* returns format 02-06-2020 */
    $entries_filtered = array_filter($entries, function ($var) use ($highestdate_entries) {

        return date('d-m-Y',(strtotime($var->pubDate))) === $highestdate_entries;       /* -> returns 1 */
    });

    //Reset the array so eg. id 10 moves to id 0
    $entries_filtered = array_values($entries_filtered);
    //Count the amount of items, so the for loop can be adjusted to that
    $numberofitems_entries = count($entries);
    $numberofitems_entries_filtered = count($entries_filtered);
    //echo "Items in entries : " . $numberofitems_entries . "<br>";
    //echo "Items in entries_filtered : " . $numberofitems_entries_filtered . "<br>" ;
    //echo "Latest date in entries : " . $highestdate_entries . "<br>" ;
    //echo strtotime($entries_filtered[0]->pubDate) . " === " . strtotime($dateoftoday);

    // XML feed provides 50 items per feed. Total is 100 items.

    // $dateoffeed=strftime("%d-%m-%y",strtotime($entries[0]->pubDate));
    // echo $dateoftoday;
    // Date format in xml feed:     Thu, 28 May 2020 12:17:38 +0200
    // Date format from date:       Mon, 01 Jun 2020 10:13:48 +0200
    // $dateoftoday=date(DATE_RFC2822);

    function showrssitem($i) {
        global $entries_filtered;
        $backgroundbutton = 'd3d3d3';
        switch ($entries_filtered[$i]->category) {
            case "Chargenrückrufe" :
                $backgroundbutton = 'ff9933';       /* orange */
                break;
            case "Rückrufe" :
                $backgroundbutton = 'ff9933';       /* orange */
                break;
            case "Informationen der Institutionen und Behörden" : 
                $backgroundbutton = 'ff3300';       /* red */
                break;
            case "Informationen der Hersteller" : 
                $backgroundbutton = 'ff5500';       /* red 2 */
                break;
            case "AMK-PhaGro-Schnellinformationen" : 
                $backgroundbutton = 'ff7700';       /* red3  */
                break;
        }

        $strippedentry1 = str_replace ("Online-Nachricht: ","", $entries_filtered[$i]->title); 
        $strippedentry2 = str_replace ("Informationen der Institutionen und Behörden: ","", $strippedentry1); 
        $strippedentry3 = str_replace ("Informationen der Hersteller: ","", $strippedentry2); 
        echo '<td style = "border=0px !important; width:20%"><a style="text-decoration: none;" target="_blank" href="' . $entries_filtered[$i]->link . '"><button style="background-color: #' . $backgroundbutton . '; margin-bottom: 0px; width: 100%; height:50px; display: block; border-radius: 10px;">' . $entries_filtered[$i]->category . '</button></a></td>';
        echo "<td><i>" . strftime('%d/%m/%Y', strtotime($entries_filtered[$i]->pubDate)) . ":</i>&nbsp;&nbsp;&nbsp;";
        echo mb_strimwidth($strippedentry3,0,200,"...") . '</td>';
    }

    ?>
