I don't know what I can do now , Please try to give me the solutions as soon as possible. Thanks My error happens on line #81 I closed everything down last night and it was all fine, website was working as normal etc, but I've turned on the Xxamp server today and I am getting this error. Seems very random as nothing has changed since it was last on? Does anyone know how to sort this out and why I'm now getting this error? Thanks! I am making some kind of licensing system and want to read a key value from the registry that identifies the PC of the client. I found some code on the internett, but which doesn't work, and I was hoping someone could explain me why. I want to read the key from the following address: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid. I am fully aware that this value can be changed, but I can use it anyway. I have found two methods. The first is the following:
$Wshshell= new COM('WScript.Shell');
$data= $Wshshell->regRead('HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid');
echo $data;
And this is the second one:
$keyhandle = reg_open_key('HKEY_LOCAL_MACHINE', 'Software\Microsoft\Cryptography\MachineGuid');
$value = reg_enum_value($keyhandle,1);
echo $value;
What am I missing to make these work, or are there other way to do it? Thanks in advance. Sincerely I'm trying to teach myself OOP PHP, and I've been looking up a number of tutorials on how to to make OOP MVC frameworks. I came across this one (cached version - their site is down at the moment of posting), and noticed something interesting about it that I've not seen in other tutorials.
Basically, it creates a registry class as $registry (which just uses the __set and __get functions to populate an initially empty array), and then stores variables in there. After that, $registry is passed on to the other classes via their __construct functions, so that they can access site-wide variables.
I think I understand how it's working, and see how it can be used, but this tutorial is the only time I've found such a thing. I was wondering, is using such a class good practice, or how should I store and access globally needed variables (like configuration, database connections, etc)?
:-\Have been reading a few places about how to set php.ini file to be able to use MySQL on my Yahoo website. But am also warned to avoid tampering needlessly with registry. So I need an absolute precedure, with port 465, I also know. Embarassing how long this has taken me to find some of this out! Thanks, Yshua Trying to improve my script-architecture, I got curious about other ways to pass application-data around aside from using the$GLOBALS array. The only other way I really found was to use an object called a "Registry". I just ended up being confused regarding when which method is better than the other, let alone how to even use a registry-object in my scripts. So my questions a - When is it better to use a registry object in place of global data? - how would you use a registry? - how would a registry object get passed around, through other objects and functions? Heres the registry I found... class registry { var $_cache_stack = array(); function __construct(){ $this->_cache_stack = array(array()); } function set($key, &$item){ $this->_cache_stack[0][$key] = &$item; } function &get($key){ return $this->_cache_stack[0][$key]; } function isEntry($key){ return ($this->getEntry($key) !== null); } function &instance(){ static $registry = false; if (!$registry) $registry = new Registry(); return $registry; } function save(){ array_unshift($this->_cache_stack, array()); if (!count($this->_cache_stack)) exit('Registry lost!'); } function restore(){ array_shift($this->_cache_stack); } } here's the class im using Code: [Select] <?php # Name: Database.singleton.php # File Description: MySQL Singleton Class to allow easy and clean access to common mysql commands # Author: ricocheting # Web: http://www.ricocheting.com/ # Update: 2010-07-19 # Version: 3.1.4 # Copyright 2003 ricocheting.com /* This program is free softwa you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

I'm new to OOP and straight out the gate Dreamweaver keeps giving me an error which I do not understand. I get that $_POST creates an array, however, in the procedural world I have always been able to assign a $variable to a $_POST. In fact if I remove the Class declaration the error goes away. What am am I missing ? - Many Thanks VJ : Code: [Select] <?php class LookUp { $first_name = $_POST["f_name"]; $last_name = $_POST ["l_name"]; $company = $_POST["company"]; } ?> I wanted to inherit child classes from parent class.

I am having some troubles and was hoping someone could guide me through it.
Q: When ever I try call my get_status function all I get is a white page of nothing, no errors to work from etc... Can anyone here see what I am doing wrong?
PATH: index.php
NOTICE //<<-- KILLS PAGE
<?php
spl_autoload_register(function ($class) {
include '/lib/' . $class . '.inc';
});
$servers = new servers;
echo $servers->get_servers();
echo "STATUS: ".$servers->get_status("0.0.0.0",80); //<<-- KILLS PAGE
?>
Page works fine until I want to use the status function, I get no errors or anything just a blank page.
PATH: Lib/Servers.inc
NOTICE //<<-- KILLS PAGE
<?php

while ($row = $res->fetch_assoc()) {
$message .= $row['HostGame'] . '<br>';
$message .= $row['HostIP'] . '<br>';
$message .= $row['HostPort'] . '<br>';

}
}
$message .= "<br>End of the \"Server List\" ";
return $message;
}
public function get_status(&$ServerIP,&$ServerPort){
