There are times when you have to change the login link in your webpage to a logout link when a user successfully logged in.

Here is a simple way to do it in PHP

Suppose your menu is

Link 1
Login
Link 2

the corresponding HTML code will look like

<a href='somepage.php'>Link 1</a>
<a href='login.php'>Login</a>
<a href='some_other_link.php'>Link 2</a>

After successful login most probably you will set a session. Say the name of the session variable is username
Then the code for the menu will look like

<a href='somepage.php'>Link 1</a>
<?php
if(isset($_SESSION['username']) && $_SESSION['username']!="")
{
echo("<a href='logout.php'>Logout</a> ");
echo($_SESSION['username']);// displays username
}
else
{
echo("<a href='login.php'>Login</a> ");
}
?>
<a href='some_other_link.php'>Link 2</a>

and also make sure to add

<?php
session_start();
?>

on top of your page.
