I am trying to create an if else statement where if the "if" part is true, a menu icon is displayed that says "Registration" and takes the user to a registration page. If the "else" part is true, the menu will display the user's name that is registered. I have attached basically how I would like it to look, I just do not know how to incorporate my div into a PHP if else statement.
<?PHP
session_start();
if ($_SESSION['email'] == '')
{
"<div id='cssmenu'>
<ul>
<li>
Registration
</li>
</ul>
</div>"
}
else
{
"<div id='cssmenu'>
<ul>
<li>
<a> "Greetings " . $_SESSION['fname'] </a>
</li>
</ul>
</div>"
}
?>

Answer 1

The following should do the trick. As mentioned by #Ghost, you need echo and you needed to change a few quotes to single quotes.
<?PHP
session_start();
if ($_SESSION['email'] == '')
{
echo "<div id='cssmenu'>
<ul>
<li>
<a href='registration.php'> Registration</a>
</li>
</ul>
</div>";
}
else
{
echo "<div id='cssmenu'>
<ul>
<li>
Greetings " . $_SESSION['fname'] . " </a>
</li>
</ul>
</div>";
}
?>

Answer 2

you can use php whitin html
the php code is only considered between php tags so anything else is put directly to browser
as i can see only one part of your html changes so a better design would be
<?php session_start(); ?>
<div id="cssmenu">
<ul>
<li>
<?php if ($_Session['email']=='') {
?>
Registration
<?php }else{ ?>
Greetings -> <?php echo $_SESSION['fname']; ?>
<?php }?>
</li>
</ul>
</div>
