<DOCTYPE html> <html> <?phpinclude 'includes/head.php'/?> <body> <?phpinclude 'includes/header.php'/?> </body> </html>
am running this code but it is not loading the include files of header and head
header
<header> <h1 class="logo">logo</h1> <nav> <ul> <li><a href="index.php">Home</a> <li><a href="downloads.php">Downloads</a> <li><a href="complains.php">complains</a> <li><a href="contact.php">Contact us</a> </ul> </nav> </header>

head
<head> <title>research perefct</title> <meta charset ="utf-8"> <link rel="stylesheet" href="css/screen.css"> </head> 

You have this <?phpinclude 'includes/header.php'/?> which should be this <?php include 'includes/header.php'; ?>
