Cookie Array Question

I have set my cookies as an array so that all the info is stored in 1 cookie.

Code:


<?php  setcookie("ptdetails[user]", "$user", time()+60*60*24*30, "/");   
       setcookie("ptdetails[pword]", "$pword", time()+60*60*24*30, "/");  
 setcookie("ptdetails[usertype]", "$usertype", time()+60*60*24*30, "/");  
 setcookie("ptdetails[secure]", "$secure", time()+60*60*24*30, "/");  
 setcookie("ptdetails[pagestyle]", "$pagestyle", time()+60*60*24*30, "/");   

header('Location: index.php') ?>

Now I am trying to get the information out of the cookies and so far having no luck.

Code:

if(!isset($user) OR !isset($pword) OR !isset($usertype) OR !isset($secure) OR !isset($pagestyle)) {  

  print_r($_COOKIE);  

echo("<hr />");

  foreach ($_COOKIE['ptdetails'] as $name => $value) {  
         echo "$name : $value <br />\n";  

  $value = $ptinfo[$name];;   

  }  

echo("<hr />");

print_r($ptinfo);

 }

I've looked through the php documentation on both cookies and arrays but I cannot find the answer to the problem I'm having. Anyone's help would be appreciated.

By the way. When I tested it using the print_r($_COOKIE); and the echo "$name : $value <br />\n"; I got the following:

Quote:

Array ( [ptdetails] => Array ( [user] => Josh [pword] => something [usertype] => admin [secure] => true [pagestyle] => default ) )

user : Josh
pword : something
usertype : admin
secure : true
pagestyle : default

Why not just use normal names? i.e;

setcookie(USER, "$user", time()+60*60*24*30, "/");
setcookie(PWORD, "$user", time()+60*60*24*30, "/");

...etc.

Then just call it with;

$_COOKIE[USER]

Unsure

Because I wanted the cookies to be stored in 1 array. It's all good though, I got it to work, it was actually quite simple. To get the array from within the array I just had to do the following:

$ptdetails = $_COOKIE[ptdetails];

$user = $ptdetails[user];
$pword = $ptdetails[pword];
$usertype = $ptdetails[usertype];
$secure = $ptdetails[secure];
$pagestyle = $ptdetails[pagestyle];

And yes, this took me a few hours to figure out with guess and check :P

But I've got another question now... I have read some documentation for the count_chars function. When I try this function, I get an array as my result instead of just the result. So I followed an example that used mb_strlen() instead. When I did this I got the following error:

Fatal error: Call to undefined function: mb_strlen() in c:\apache\htdocs\_other\presenttruth_new\test.php on line 4

If anyone could explain why I'm getting an array or why I'm getting this error, it'd be helpful.

No prob. Regarding your other question, have you considered strlen() ?

Code:
<?php 
$str = 'abcdef'; 
echo strlen($str); // 6 

$str = ' ab cd '; 
echo strlen($str); // 7 
?>

Hope that helps.
