Hi

Ope u r fine and I can tell u wh@ u r doin wron'

Cookie information cannot be sent after any text has been displayed[1].
That's one of the most common mistakes. Test for it!
The following code works on my php test machine (PHP 4.2.3).

Code:

&lt;?php
if (!isset($_COOKIE['cookie']))	{
        setcookie ("cookie[three]", "cookiethree");
	setcookie ("cookie[two]", "cookietwo");
	setcookie ("cookie[one]", "cookieone");

    echo("Never ever echo something before setting the cookies!&lt;br&gt;");
    echo("Refresh to show the content of cookies.&lt;br&gt;&lt;hr&gt;");
}	


if (isset($_COOKIE['cookie'])){
	
   foreach ($_COOKIE['cookie'] as $name =&gt; $value) {
        echo "$name : $value &lt;br /&gt;\n";
    }

    print_r($_COOKIE);
}
	
 phpinfo();
?&gt;

Cheers

Thanx 4 ur reply sec_ware!

Although I do call the setcookie() function b4 I echo any output to the browser.

I am using a Windows XP pro box, and IE to attempt to view my web-pages, therefore I am not sure whether it is sumthin to do with IE th@ is stoppin me from creatin cookies on my machine (hence the many "." in the cookie name).

Hi TTAYO

Interesting. Let's track down the problem:

1) Client-side: Have you disabled cookies on IE?
2) Client-side: Have you tried firefox (user cookie management is superior to IE in my opinion)?
3) Server-side: What is your WebServer and PHP version?
4) Server-side: Have you tried my example (cut and paste into a .php file and load it in IE (no <HTML> etc)?
5) Server-side: Could you attach (as txt-file) the full content of your server-side setcookie-file?
6) Client-side: You can try to intercept the server-client communication[1]?

Sorry th@ it has taken some time to reply!

I hav found out th@ the problem with my script wz th@ I wz not setting an experation time, because as long as I set and experation time then the script does create a cookie on my machine.

I not sure if this is a limitation of IE or of the web host th@ I am using, bt the problem is now solved.

Thanx 4 ur help anyway,
L8R, TTAYO
