何かを変更しようとすると、タイトルに記載されているエラーが発生します。調べてみましたが、見つけた答えがよくわかりません。このエラーの原因とその修正方法。たとえば、href リンクを変更しようとしたところ、原因がわからないままこのエラーが発生しました。PHPコードヘッダーの順序に関係があると考える前は、常に本文の前に移動する必要があり、その後はヘッダーを変更できなくなりました。しかし、href リンクのような小さなことが原因である場合は、別のことが起こっています。

警告: ヘッダー情報を変更できません - /home/ の (/home/nieuwsman/domains/cdwp.publiceer.net/public_html/wp-content/themes/wpoupon_mollie/ideal.class.php:1 で開始された出力) によって既に送信されたヘッダーnieuwsman/domains/cdwp.publiceer.net/public_html/wp-content/themes/wpoupon_mollie/functions.php 28 行目

function wpoupon_redirect_to_mollie() {

    require_once('ideal.class.php');

    if (!in_array('ssl', stream_get_transports()))
    {
        echo "<h1>Foutmelding</h1>";
        echo "<p>Uw PHP installatie heeft geen SSL ondersteuning. SSL is nodig voor de communicatie met de Mollie iDEAL API.</p>";
        exit;
    }

    $partner_id  = 823997; 
    $amount      = $_POST['amount']; 
    $description = $_POST['item_name'];
    $return_url  = $_POST['return'];
    $report_url  = $_POST['notify_url'];

    $iDEAL = new iDEAL_Payment($partner_id);
    //$iDEAL->setTestMode();

    if (isset($_POST['bank_id']) and !empty($_POST['bank_id'])) 
    {
        if ($iDEAL->createPayment($_POST['bank_id'], $amount, $description, $return_url, $report_url)) 
        {           
            header("Location: " . $iDEAL->getBankURL());
            exit;   
        } else {
            echo $iDEAL->getErrorMessage();
        }
    }

}

たとえば、28行目のエラー

しかし、コードの一部だけを修正したくはありません。それがどのように機能するかを知りたいのです。
