Re: [PHP] Re: Think I found a PHP bug
This is fixed in PHP 5.4 by completely dropping support for the TZ
environment variable. PHP will always use UTC unless you explicitly set
it to something. It won't matter which timezone the system is running
in. This is the only reliable way to always have consistent behaviour
across all environments.

We have a utility disk that we use for a variety of things where I work and some of them are DOS based. We use the purely DOS ones rarely enough these days that people have trouble remembering how to use them. I wanted to see if it would be possible to write a menu type front end that would detect what OS it is running under and present the tools and options that are suitable for that OS. My thought was to use PHP because it is cross platform (to some degree) and then in theory the disk could be run under anything that can run PHP and anything that would run under the current OS can then be presented to the end user. If there is a better solution than PHP I'm open to it, but I already know PHP so I figured that would make it easier. Basically I need to be able to present a menu to the end user so they can select the tool they want to run. We currently have tool disks for DOS, Windows and OSX. If I could combine them into one big disk/usb key I would be a hero around these parts. Matt -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

None of the older regulars here are from the area (I'm probably closest, up in Scranton), but one of the newer folks may be.

You don't say what the db class (in db.php) itself does other than wrapping the
database-specific classes, so I've assumed it doesn't do anything. If it does
do more then simply have the mysql, oracle, etc classes extend db.
I've also assumed that the application doesn't need to support multiple
database types simultaneously.
class application
{
public $db = null;
function __construct($db = 'mysql')
{
require __DIR__.'/db/'.$db.'.php';
$this->db = new MySQL();
}
}
$test = new application('mysql');
$test->db->connect();

[PHP] OOP problems
Hello, I would like to ask you for help. This days I am trying to build one of my applications. But I have problem which stopped me. I have folder whit php files like connect.php, delete.php etc. These files contains classes named the same as files. So in file connect.php is class Connect. These files are placed in folder named mysql and this folder is inside folder named db. In folder db is a php file named mysql.php, in this file I include classes from folder mysql, after include I declare class MySQL and in it I have method __construct(). In this method I create dynamic objects from included classes. And this is the problem that I can not solve, I have more then one of this files(mysql.php[whit class MySQL], oracle.php[whit class Oracle] etc.) and I need to include them to file called db.php that is in the main folder of my app. In db.php is an class called db, how can I add classes MySQL, Oracle etc. to class db? I try to use abstract class whit __set and __get methods but I also need to include class db to main class application. I am really sorry for my English, so please be indulgent. So I need to connect classes like this: application->db->mysql->connect, but I can not use extends because in php you can have only one parent class. The reason why I am trying to do something like this is because I want to call methods like this: $test = new application(); $test->db->connect(); If it is mysql or othet database I set in config.php file. Can you help my please? Sincerely, Dominik Halvonik

But I have no idea what compiler could be used. MSDOS has no built in network support, so advanced memory management, etc. Not without having to load additional drivers and the TCP/IP drivers for MS DOS are not tiny. Sure, you really can (and I have) cram then into upper memory, but it is on a motherboard by motherboard basis - one size does not fit all. All of these things would severely cripple PHP's usage in a true MSDOS environment. Add to that, the vast majority of libraries will be talking to the windows api in some form and that doesn't exist. You are pretty much stuck with no network services, limited memory and restricted extensions. Can you describe your project and to why it MUST run on such an ancient OS?
