[SOLVED] What am I doing wrong?

[060_VCW_606]

I'm trying to program a small system on my site revolving around the number count generated by a Perl script and output into a single-numbered text file.  I'm using cookies; throughout the site (which is in PHP; the Perl part is not important in this matter), the computer compares the value in the cookie and the value on the text file to decide what to show:

 

<?php

$record = $HTTP_COOKIE_VARS["record"];

$file = "http://vcw.vali-ent.com/roleplays/count.txt";

$count = fopen($file, 'r');

$data = fread($count, 5);

fclose($count);

if (isset($_COOKIE['record'])){

if ($record > $data){

print("NEW!");

} else {

print("No New");

}

} else {

print("Not Set");

}

?>

 

My plan is to have the number update on a certain page using an iframe.  And that the iframe only contains this snipet of code:

 

<?php

$file = "http://vcw.vali-ent.com/roleplays/count.txt";

$count = fopen($file, 'r');

$data = fread($count, 5);

fclose($count);

setcookie("record",$data,time()+604800);

?>

 

The only problem is that the second portion of code doesn't work.  Does anyone know what I'm doing wrong?

Define "doesn't work".

 

Also, throw out your book and buy a new one. $HTTP_COOKIE_VARS has been deprecated for a loooong time.

Execution of the second snipet returns this:

 

Warning: Cannot modify header information - headers already sent by (output started at /home/valicom/public_html/test/boardinclude.php:1) in /home/valicom/public_html/test/boardinclude.php on line 6

You're probably using "setcookie" after you've already sent something to the browser.  That function has to be used before any HTML is written or PHP outputs anything to the page.

[060_VCW_606]

The snipet with setcookie() is the only code in the PHP file.

[Daniel0]

It says the output was sent on line 1. Make sure you haven't accidentally slipped in whitespace before the PHP opening tag.

[060_VCW_606]

There's no whitespace.  I still have that output.

I figured it out, and I changed the deprecated part of the first snippet.
