rowCount()作为一个变量，或者直接包含在if语句中，这样更好

我见过有人这样使用rowCount…

if ($q -> rowCount() < 1) {
   ....
}

这是我如何使用它的大部分我的问题是，虽然如果你有多个elseif语句是更好地将其存储在一个变量作为rowCount不会被调用不止一次??像这样…

if (isset($_GET['action']) && $_GET['action'] === 'addhotlink') {
    $q = $dbc -> prepare("SELECT * FROM hotlinks WHERE id = ?");
    $q -> execute(array($details['id']));
    $result = $q -> rowCount();
    if ($result < 3) {
        echo '<p>Choose a name for your hotlink (max 15 characters):</p><p><form action="/success?action=hotlink" method="post"><input type="text" name="link_name" maxlength="15" /></p><input type="hidden" name="addhotlink" value="' . $_SERVER['HTTP_REFERER'] . '" /><p><input id="submit" type="submit" value="Add Hotlink" /></p></form>';
    }
    elseif ($result < 10 && $details['subscriber'] > 0) {
        echo '<p>Choose a name for your hotlink (max 15 characters):</p><p><form action="/success?action=hotlink" method="post"><input type="text" name="link_name" maxlength="15" /></p><input type="hidden" name="addhotlink" value="' . $_SERVER['HTTP_REFERER'] . '" /><p><input id="submit" type="submit" value="Add Hotlink" /></p></form>';
    }
    elseif ($result > 9 && $details['subscriber'] > 0) {
        echo '<p>You have already used your maximum number of 10 hotlinks.</p>';
    }
    else {
        echo '<p>You have already used your maximum amount of hotlinks allowed for non subscribed members.</p><p>To get more please <a href"#">subscribe</a>.</p>';
    }

哪个更好，为什么??
