I've got this script:

<html>

<head>

<title>Hi User</title>

</head>

<body>

<h1>Hi User</h1>

<?php

if (empty($userName)){

print <<<HERE

<form>

Please enter your name:

<input type = "text"

name = "userName"><br>

<input type = "submit">

</form>

HERE;

} else {

print "<h3>Hi there, $userName!</h3>";

} //end

?>

</body>

</html>

 

 

I've got apache 2.2.4 and php 5.2.3

I type in my name but nothing happens and my name disappears...

usually I have to write $_POST[something]

For a start you need to have <form action='yourscript.php' method='post'> that deals with recieving the data.  Then you need to assign the data to the $var like $username = $_POST['username']; in your script and make it global so your html can find it by putting global $username at the top of yourscript.php

 

Please go and read w3c schools on html forms and php so you will understand
