PHP mysqli高于和低于一个数[关闭]

Question

I have a simple bit of loop code though I have an issues with it. I'm trying to create a condition where if a number in a field is in between two numbers but get a syntax error.

foreach($data as $nav) {
    if ($nav['main_nav'] > 9 && < 15) {
        echo "<li>
             <a href='" . $nav["url_slug"] . "'>" . $nav['title'] . "</a>
        </li>";
    }
}

Answer 1

you have to explicitly put the second condition

foreach($data as $nav) {
    if ($nav['main_nav'] > 9 && $nav['main_nav'] < 15) {
        echo "<li>
            <a href='" . $nav["url_slug"] . "'>" . $nav['title'] . "</a>
        </li>";
    }
}
