    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:
    <?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!<br>");
        echo("Refresh to show the content of cookies.<br><hr>");
    }	
    
    
    if (isset($_COOKIE['cookie'])){
    	
       foreach ($_COOKIE['cookie'] as $name => $value) {
            echo "$name : $value <br />\n";
        }
    
        print_r($_COOKIE);
    }
    	
     phpinfo();
    ?>

    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]?

    Cheers

    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
