Why won't this script recognize the parameter?

Posted on 2008-06-17

I am calling this script by the following statement (in a browser):

It was working fine on a Windows server; I just switched to a Linux server and now this...
$COUNT_FILE = "data.txt";  // En: Absolute path and name to count data file.
function error ($error_message) {
    echo $error_message."<BR>";
echo $QUERY_STRING."<br>";
$url = urldecode($QUERY_STRING);  //  get the passed URL
if (! file_exists($COUNT_FILE))
    error("Can't find data file, check '\$COUNT_FILE' var...");
if ((! $url) || (! preg_match("/http:/", $url)))
error ("The URL you passed is invalid (doesn't begin with http:)");
$file_arry = file($COUNT_FILE); //  read each line of data from count.txt file into array
//list($key, $val) = each($file_arry);
//echo "key=".$key."<BR>";
//echo "val=".$val."<BR>";
while (list($key, $val) = each($file_arry)) {  //  parse each line into key/value pairs
    if ($val != "") {  //  if URL is not blank...
        list($file_url, $nb) = preg_split("/\t|\n/", $val);
        if ($file_url == $url) {
           $nb += 1;
           $file_arry[$key] = "$file_url\t$nb\n";
           $find = 1;
$file = join ("", $file_arry);
//if (! $find)  //  if URL wasn't found, put new URL into file
//   $file .= "$url\t1\n";
$fp = fopen("$COUNT_FILE", "w");
flock($fp, LOCK_EX + LOCK_NB);
fputs($fp, $file);
flock($fp, LOCK_UN);
header("Location: $url");

Instead of:
$url = urldecode($QUERY_STRING);

$url = urldecode($_SERVER['QUERY_STRING'] );

IF that does not work, try passing it as:

and to retrieve the value use:

maybe your script relies on register_globals to be turned on?

Provide the full path to the file. So if the file resides on:

$COUNT_FILE = "C:\\Test\\data.txt";

Hmmm... deleted the file (because it was old, and will upload new ones tonight when I get home) and am now getting this warning:

Warning: Cannot modify header information - headers already sent by (output started at /home/wwwmar1/public_html/clickCounter/count.php:10) in /home/wwwmar1/public_html/clickCounter/count.php on line 47

What do I do to fix this?
