Creating a Non-Existant File on Linux

[JCScoobyRS]

I use this code:

<?php
    $fname = $HTTP_POST_VARS['filename'];
    $ftext = $HTTP_POST_VARS['code'];
    $oldurl = $_SERVER[HTTP_REFERER];
    $fp = fopen($fname,"r");
    if ($fp)
    {
        header("Location: badname.php");
    }
    else
    {
        echo "The file ".$fname." does not exist";
        $fp = fopen($fname,'a');
        fwrite($fp,$ftext);
        header("Location: $fname");
    }
?>

on Windows to see if a file is there and if not, create it and write to it. On Linux, I get these errors:

Warning: fopen(Nothing.php) [function.fopen]: failed to create stream: No such file or directory in /home/eampets/public_html/ushops/createfile.php on line 5
The file Nothing.php does not exist
Warning: Cannot modify header information - headers already sent by (output started at /home/eampets/public_html/ushops/createfile.php:5) in /home/eampets/public_html/ushops/createfile.php on line 15

createfile.php is the code I posted first. Can anyone see what changes must be made to get this to work? Thanks, Jeremy

Do you have anything above you <?php code ?> (like any html)? If so get rid of that or code it all in php and that should fix your problem. .. if not could you post all your code from that page?

That is all the code for the createfile.php. There is an HTML file that calls the createfile.php on submit but that shouldn't matter. Since I have no more code in createfile.php, what else do you need to help me out? Thanks for your time, Jeremy

Change the mode with which you are creating your file.
In:
fopen($fname,"a");

change to:
fopen($fname,"w");

The "a" tells the operating system that you are opening the file for appending, and while Windows doesn't care too much if the file doesn't exist (it just creates it anyway), Linux is a bit more picky and won't try to create a file that you are trying to open for appending.

Did that make sense?
