How to assign the .active class to the first element of an array using a foreach loop?

Question

PHP

Detailed, I have a multidimensional array this is a navigation menu

$menu = [
    ['link'=>'Домой', 'href'=>'index.php'],
    ['link'=>'Новости', 'href'=>'news.php'],
    ['link'=>'Оплатить', 'href'=>'pay.php'],
    ['link'=>'О нас', 'href'=>'about.php'],
    ['link'=>'Контакты', 'href'=>'contact.php']
];

I output it through a foreach loop

foreach($menu as $val){
    echo "<li> <a href={$val['href']}>{$val['link']}</a> </li>";
}

But I want to prescribe that the first element, the main page, was assigned the .active class to assign the css of the active page.

Answer 1

Well, if it's simple, then you can do it like this:

$first = true;
foreach($menu as $val){
    echo "<li " . ($first ? ' class="active"' : '') . "> <a href={$val['href']}>{$val['link']}</a> </li>";
    if ($first) {
       $first = false;
    }
}

Or like this:

foreach($menu as $val){
    echo "<li " . ($menu[0]['href'] == $val['href'] ? ' class="active"' : '') . "> <a href={$val['href']}>{$val['link']}</a> </li>";
}

Answer 2

<?php foreach ($menu as $key => $value) : ?>
  <li <?if (!$key) :?>class="active"<?php endif;?>><a href={$val['href']}>{$val['link']}</a></li>
<?php endforeach ;?>
