PHP - Possible Php Bug With Fopen() And Fwrite()?

$DOCUMENT_ROOT=$_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.
Code: [Select]

Hey guys,


I have a script that is run once a week to fetch some user info for a large number of accounts.
The code I have now writes the info correctly, but I was wondering if there was an easy way to have the accountdata.txt file completely wiped before new updated info is written to it, as opposed to deleting it manually every week.

        $FileName = "accountdata.txt";

$f=fopen($FileName,"a+");

fwrite($f, $UserKey[$i]." ".$SigKey[$i]."\n");

$f=fclose;


I could in theory just open the file and delete everything in it manually, save it and then run this script, but I'm always looking for more ways to make things efficient, and come a time when it's run more than once a week it'd be nice to have all that automated.

So in summary, I need it to delete all data (if any) from the accountdata.txt file before it writes anything to it.

Thanks.

Can't figure out why the page wont save after clicking save.

$KOHDE="index.php?s=admin";
$LOMAKE_W = 400;
$TEXTAREA_W = 50;
$TEXTAREA_H = 20;
$LOMAKE = mysql_real_escape_string($_GET["l"]);
$LOMAKE2 = mysql_real_escape_string($_POST["lomake"]);

after a few more lines...

elseif ($LOMAKE2 == "etusivu"){ #Etusivun muokkaus
$teksti = stripslashes($_POST["teksti"]);
$f = fopen("etusivu.php", "w");
fwrite($f, $teksti);
fclose($f);
}
elseif ($LOMAKE == "etusivu"){ #Etusivun muokkaus
echo "<h1>Edit home page</h1>";
$f = file("etusivu.php");
echo "<form action='$KOHDE' method='post'>
<textarea name='teksti' cols='$TEXTAREA_W' rows='$TEXTAREA_H'>";
for ($i = 0; $i < count($f); $i++){
$f[$i] = str_replace("\"", "''", $f[$i]);
echo $f[$i];
}
echo "</textarea>
<input type='hidden' value='etusivu' name='lomake'/>
<br><input type='submit' value='Save'/>
</form><br/>";
html_ohje();
}

I can't see where it has gone wrong. Can anyone help?
