PHP - Writing Code To A Page Created With Fopen/fwrite

Alright so I'm attempting to save config data via php. Bellow is the code I currently have, however I'm afraid that when I "flip the switch" and use it that it will error out because of the <?php and ?> tags inside of it... Ideas, suggestions?


$config = '../includes/config.php';
$fh = fopen($config, 'w');
$data = '
<?php

$dbhost = "'.$database_host.'";
$dbuser = "'.$database_username.'";
$dbpass = "'.$database_password.'";
$dbname = "'.$database_name.'";

$key = "'.$site_key.'";
$cron_key = "'.$database_cron_key.'";
?>
';
fwrite($fh, $data);
fclose($fh);

Greetings all,

I'm completely stumped...so I'd like to run this issue by you guys (and gals!).
I have encountered an odd issue, and I have no idea why this is doing what it's doing.

When I execute the following code, all by itself, in an "index.php" file (with no other files around...completely isolated!)
I get a result of "testtest" 


$log_file = 'all.txt';
$handle = fopen($log_file, 'a');
fwrite($handle, 'test');
fclose($handle);


Note: I delete the file each time I execute the script (in a browser). I am also the only one running this script.

I've tried running on PHP 5.2.x and PHP 5.3.x
I have also tried on my machine as well as a separate, remote machine.

Is the script running twice?
If so, what's causing it?

Any help is appreciated as always!

$DOCUMENT_ROOT=$_SERVER['DOCUMENT_ROOT'];

$outputstring = $date."\t".$tireqty." tires \t".$oilqty."oil\t".$sparkqty."
                spark plugs\t\$".$totalamount."\t".$address."\n";

//open file for appending
@$fp = fopen('$DOCUMENT_ROOT/../orders/orders.txt', 'ab');
if (!$fp)
{
    echo '<p><strong>Your order can not be processed at this time.
                    Please try again later</strong></p></body></html>';
    exit;   
}
//write to file 
fwrite($fp, $outputstring, strlen($outputstring));
flock($fp, LOCK_UN);
fclose($fp);


Can someone please explain to me why this Code is giving me the error?
i've tried to take out $DOCUMENT_ROOT and specify where exactly i want the file to be /dir/dir/file.txt
but it still gives me an error.

I'm trying to create an online web editor. It works fine for opening and writing files on the same server where the web editor is hosted, but I want it to be able to get_file_contents, fopen and fwrite files on a remote server, logging in with ftp_connect and ftp_login. I've noticed the functions ftp_get and ftp_fget but I'd rather not create another local file, if possible I want to open the remote file directly into a <texarea> then save it directly back to the remote server. Is this possible? So far I just get errors... 

Here's an example of the code I'm trying to combine, to retrieve the contents of a file on a remote server and put them in a <textarea>:

Code: [Select]
<?php

    $conn = ftp_connect("ftp.domain.com");
    ftp_login($conn, "username", "password");
    ftp_pasv($conn, true);

  $filename='example.php';

// open file 
  $fh = fopen($filename, "r") or die("Could not open file!"); 

// read file contents
  $datax = fread($fh, filesize($filename)) or die("Could not read file!");
  $data=htmlspecialchars($datax);

// close file
  fclose($fh);

// close this connection
  ftp_close($conn);

echo '<textarea cols="200%" rows="50">'.$data.'</textarea>';

?>
And another failed example:

Code: [Select]
<?php

  $filename='editor.php';

  $fh = fopen("ftp://username:password@domain.com/example.php", "r") or die("Could not open file!"); 

  $datax = fread($fh, filesize($filename)) or die("Could not read file!");
  $data=htmlspecialchars($datax);

  fclose($fh);

echo '<textarea cols="200%" rows="50">'.$data.'</textarea>';

?>

I am getting a rediculous amount of errors in the log on my host saying the following but for numerous referer addresses.
