Answer 1

You can use

<?php
function active($current_page){
    $page = $_GET['p'];
    if(isset($page) && $page == $current_page){
        echo 'active'; //this is class name in css
    }
}
?>
<ul>
    <li><a class="<?php active('page1');?>" href="?p=page1">page1</a></li>
    <li><a class="<?php active('page2');?>" href="?p=page2">page2</a></li>
    <li><a class="<?php active('page3');?>" href="?p=page3">page3</a></li>
    <li><a class="<?php active('page4');?>" href="?p=page4">page4</a></li>
</ul>

Answer 2

Put all the below code in menu.php and everything will be taken care of.

// function to get the current page name
function PageName() {
  return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}

$current_page = PageName();

Use the above to get the current page name then put this in your menu

<li><a class="<?php echo $current_page == 'offnungszeiten.php' ? 'active':NULL ?>" href="offnungszeiten.php">Öffnungszeiten</a></li>
<li><a class="<?php echo $current_page == 'sauna.php' ? 'active':NULL ?>" href="sauna.php">Sauna</a></li>
<li><a class="<?php echo $current_page == 'frauensauna.php' ? 'active':NULL ?>" href="frauensauna.php">Frauensauna</a></li>
<li><a class="<?php echo $current_page == 'custom.php' ? 'active':NULL ?>" href="custom.php">Beauty Lounge</a></li>
<li><a class="<?php echo $current_page == 'feiertage.php' ? 'active':NULL ?>" href="feiertage.php">Feiertage</a></li>

where active is the name of the class which will highlight your menu item

Answer 3

adding this:<?= ($activePage == 'home') ? 'active':''; ?> to my link it works perfectly, I only can't make the child of a submenu working to make the parent active.

I have done it with php in this way,

function createTopNav($active)
{
    $pages = array(
        array(
            'name'=>'Home',
            'link'=>'index'
        ),
        array(
            'name'=>'Smartphone',
            'link'=>'smartphone'
        ),
        array(
            'name'=>'Tablet',
            'link'=>'tablet'
        ),
        array(
            'name'=>'About Us',
            'link'=>'about'
        ),
        array(
            'name'=>'Contact Us',
            'link'=>'contact'
        )
    );
    $res = "<ul>";
    $activePage = "";
    foreach($pages as $key=>$val)
    {
        if($val['link']==$active)
        {
            $res.= "<li><a href='".$val['link']."'  class='active'  >".$val['name']."</a></li>";
        }
        else
        {
            $res.= "<li><a href='".$val['link']."'>".$val['name']."</a></li>";          
        }
    }
    $res.="</ul>";
    return $res;
}

And then to call this function

echo createTopNav("about");

and the output will be like this

<ul>
   <li><a href="index">Home</a></li>
   <li><a href="smartphone">Smartphone</a></li>
   <li><a href="tablet">Tablet</a></li>
   <li><a href="about" class="active">About Us</a></li>
   <li><a href="contact">Contact Us</a></li>
</ul>

Answer 5

Create a variable in each of your php file like :

$activePage = "sauna"; (different for each page)

then check that variable in your html page like this

<?php if ($activePage =="sauna") {?>
 class="active" <?php } ?>

Answer 6

this method gets the current page using php which will pass a word in this case active and places it inside the class parameter to set the page active.

<?php
function active($currect_page){
  $url_array =  explode('/', $_SERVER['REQUEST_URI']) ;
  $url = end($url_array);  
  if($currect_page == $url){
      echo 'active'; //class name in css 
  } 
}
?>
<ul>
    <li><a class="<?php active('page1.php');?>" href="http://localhost/page1.php">page1</a></li>
    <li><a class="<?php active('page2.php');?>" href="http://localhost/page2.php">page2</a></li>
    <li><a class="<?php active('page3.php');?>" href="http://localhost/page3.php">page3</a></li>
    <li><a class="<?php active('page4.php');?>" href="http://localhost/page4.php">page4</a></li>
</ul>
