<a href=“https://www.youtube.com/c/linuxhint/”> Movies </a>
</physique>
</html>
Subsequent, I created one other PHP file with the title linuxhint.php file and used the embrace() operate so as to add the content material of the take a look at.php file on this file. The next is the code snippet:
<html>
<physique bgcolor=“White”>
<?php embrace(“take a look at.php”); ?>
<h2><b>Welcome to Linux Trace </b></h2>
