每个客户端请求都是该类的新实例？

Question

I wrote a class that builds some url in a page every time there is a client request to the server. In a hypothetical scenario in which 100 clients, at the same time, require a server connection, it should produce 100 instances of that class, right? So I would like to know what would be the result of many instances at the same time on the page and if this is a good practice to solve my problem with the "url generator". Thanks

[EDIT] What I tried to do it was to use __set() method and overloading to build the URLs. The fact is that I started to study object-oriented programming in php and I wanted to try a practical application of this method. Here is a piece of code:

 Class BuildPath { 

    private $ServerPath;
    private $ServerUrl;
    private $UrlPath;
    private $data;

    function __construct()
    {
        $this->ServerPath = $_SERVER['DOCUMENT_ROOT'];
        $this->ServerUrl =  $_SERVER['HTTP_HOST'];
        $this->UrlPath = $_SERVER['REQUEST_URI'];
        $this->data = array();
    }

    public function __get($key) {
            return $this->$key;
    }

    public function __set($key,$value)
    {
        $this->data[$key] = $value;
    }

    // others methods

After reading some of the comments I think you are misunderstanding what PHP is and isn't. Each time a user makes a request to the page it is "creating an instance" as you say. After the page is loaded the "instance" is removed. This is how PHP works.

Singleton classes will not share data with one users instance with another users instance but instead share that users intsance of that class with that same users instance of another class.

This is how PHP operates and is normal. Since php doesn't "store" data between each request this is where memcache or mysql come into use or sessions.
