So I'm writing an install script for my blog software, however there seems to be an error in my script and I just can't find it.

CODE

<? session_start(); ?>

<body>
<?php
//Check to see if step has already been done
if($_SESSION['step'] == 1 || !isset($_SESSION['step'])) {

    if(!isset($_POST['submit'])) {

    <?php

    } else {

        $user = $_POST['user'];

            }

        echo "Successfully connected to $host.<br/><br/>";
        }
    }
} else if($_SESSION['step'] == 2) {}
?>
</body>
</html>

The error I get is:

Warning: fwrite(): supplied argument is not a valid stream resource in -edited out- on line 123
Warning: fclose(): supplied argument is not a valid stream resource in -edited out- on line 124

I have no idea why it's giving this error, as it's almost the exact same piece of code as lines 120 and 121. Yet those don't create any errors.

Any suggestions?

I've no idea what the problem is, but it's no good just staring at the code. Print out the values of $handle and $handle2. Are both being returned correctly? (Are both valid stream handles, which I think means positive integers? What is the error return from fopen() ?)

Hmm,

printing $handle gives "1", printing $handle2 gives "Resource id #3". I still have no idea what's happening though.
