[PHP] Problem with class and tree-like struct
Hello!
I made a class which should represent a tree-like structure (PHP 4.3.8).
I made a root-nore and added 2 childs. The problem is that the childs
are not added to the parent. Why?
Martin
class TreeItem
{ var $m_pParent;
var $m_sName;
var $m_arrChilds = array();
function TreeItem($pParent, $sName)
{ $this->m_pParent = $pParent;
$this->m_sName = $sName;
if ($pParent != NULL)
$pParent->AddChild($this);
}
function AddChild($pTreeItem)
{ array_push($this->m_arrChilds, $pTreeItem);
}
}
$root = new TreeItem(NULL, "Root");
$child1 = new TreeItem($root, "Child 1");
$child2 = new TreeItem($root, "Child 2");
print Count($root->m_arrChilds); // Outputs 0. Why

[PHP] How to handle cookies?
Hello! I want to use php to gather some informations on a website. You
have to login to this website. In a brwoser, a cookie is set at login
and identifies you.
How can I handle this cookie when using php? Is there an easy way? It
would be best just to use fopen("http://...";).

[PHP] Re: Testing if cookies are enabled
Hi Aidan, > Think about it. > > Step 1) Analyse the problem. > a) Set a cookie. > b) Test if the cookie has been set. > c) Display data from cookie > > Step 2) Read the fucking manual > a) http://php.net/setcookie > b) http://php.net/setcookie > c) http://php.net/setcookie thanks for your reply, I think you missunderstood, please read more carefully. I know how to set and read a cookie, but as I wrote I wasn't able to set and text a cookie ON THE SAME PAGE. The manual says: http://php.net/setcookie "Once the cookies have been set, they can be accessed ON THE NEXT PAGE." But I have seen pages on which it seems they set und check if the cookie has been set ON THE SAME PAGE. So I want to know how they do that (perhaps with a 302-header or something like that?).

[PHP] Check if cookies are enabled on one page
Hello! I don't want to alyways set a cookie when a user enters my page. I want to set it when the users logs on, not earlier. The way is: - "Login-Page": The user enters the page where he can enter his name/password in a form and then submits this form. Before this, no cookie should be set. - "After Login-Page": Here the cookie is set for the first time. - If the user has enabled cookies, I want to show him his data. - If the user has disabled cookies, I want to show him a page saying that he should enable cookies. I saw pages doing so, but how is it done? I seem not to be able to set and check a cookie on the same page (or am I wrong?)

[PHP] Testing for cookie?
Hello! Okay, I saw pages doing this and I want exactly the same: - On a page the user can login. Before, no cookie is set. - On the next page, the cookie is set. It shows either the user data (is the login was correct and cookies where enabled) or a page which tells that cookies are disabled. So how is it done? I was not able to set and test a cookie on the same page. Martin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
