Cómo cambiar el estilo de un menú activo con php + css

So, I'm writing a menu and I want it to stay a certain color based upon it being on that page. I've added "class = 'active'" onto the page, and I've tried adding it to CSS, but it's not working. Any ideas?

Código PHP: 

<?php
$currentPage = basename($_SERVER['REQUEST_URI']);
print "<div id = 'submenu-container'>";
print "<div id = 'submenu'>";
print "<ul class = 'about'>";
print "     <li><a  href='about.php#about_intro.php'if($currentPage=='about.php#about_intro.php' || $currentPage=='about.php') echo 'class='active''>About</a></li>";
print "     <li><a href='about.php#about_team.php'if($currentPage=='about.php#about_team.php') echo 'class='active''>Team</a></li>";
print "     <li><a href='about.php#about_services.php' if($currentPage=='about.php#about_services.php') echo 'class='active'>Services</a></li>";            
print " </ul>";
print "</div>";
print"</div>";
?>

CSS: 

#submenu ul li a .active {
background:#FFF;    
}

$_SERVER['REQUEST_URI'] will never contain the portion after the hash. It will only show up to about.php and any URL arguments passed with the ?. You should create specific pages for each of these, give the about_intro/about_team/about_services in a query string instead of a hash, or add the active class with javascript.

Additionally, don't use an if statement when inside of another statement. Use the ternary operator.

print "<li><a href='about.php'"
    .$currentpage=="about.php"?" class='active'":""
    .">About</a></li>";

How will I add the active class with javascript? Sorry, I'm not that experienced with JS, I picked it up as I went along, never formally taught myself. - Andrés 

print "     <li><a  href='about.php#about_intro.php'if($currentPage=='about.php#about_intro.php' || $currentPage=='about.php') echo 'class='active''>About</a></li>";

doesn't make sense. all this string will be outputted and displayed in html. you must use string concatenation:

$cl = ($currentPage=='about.php#about_intro.php' || $currentPage=='about.php')?" class='active'": "";
print "<li><a  href='about.php#about_intro.php' $cl>About</a></li>";
