I have a class called myClass in /myDir/myClass.php. When user types url:

http://mysite.com/myDir/myClass.php,

I want to automatically create an instance of myClass. What technique can I use to do this? the idea is to use myDir directory as top level of programs that user can call directly, but I don't want to add instance_of_myClass = new myClass(); because then I won't be able to extend the class. Does this make sense?

class myClass { __construct() { echo "hello World"; $this->myClass_report(); } myClass_report() { // some code here } }

.htaccess:

#if You have access, omit RewriteBase and put the rule in http.conf, #with a / in the beginning of the pattern. RewriteBase / RewriteCond $0 !=index.php RewriteRule .* index.php?path=$0 [QSA,B]

index.php

//check if the file exists and it's allowed if (!check_if_allowed_path(realpath($_GET['path']))) { //access denied; check e.g. against the document root or //something more complex } //or use autoload instead include $_GET['path']; $classname = basename($_GET['path'], '.php'); $instance = new $classname();

this sounds like what I what I am looking for, but will my post variables fall off?
@bob The POST content will be untouched by this.
$classname = str_replace(".php", "", basename($_GET['path']));

class myClass { __construct() { echo "hello World"; myClass_report(); } myClass_report() { // some code here } } $x = new myClass();

I don't understand what you're trying to do, but maybe this will help:

If you want to create an instance of myClass, but don't want the new myClass to be hard-coded everywhere, you could use a factory (wikipedia) of some kind.

If you are not creating an instance with 

$classINstance = new myClass();

Then you don't have a class instance. That has nothing to do with extending a class.

You extend a class (i assume you mean inheritance?), then you create a new class that extends a parent class. To use this class you also create a new instance with the new operator.

At least if you are not using the static keyword to create static methods for a class.

I had a quick search, maybe have a look at this questions accepted answer. Lookd like a good summary that could help you:

OOP

Or i just didn't understand what you meant ;)

Use the factory design pattern:

<?php //Factory.php include_once('Box.php'); class My_Factory { private $this->outcome; public function __construct() { this->outcome = $this->doSomeWeirdShitToSetupTheFactoryAndBlueprintSomething(); } private function doSomeWeirdShitToSetupTheFactoryAndBlueprintSomething() { //1+1 } public function giveMeAnInstanceOfOutcome() { return new My_Box($this->outcome); } }

Edit: I read it again and I have one question: Why do you want a user to type http://yourl/YourClass.php ???

Classes should be included; never ever ever used to load directly to the browser.

can I combine this idea with a factory pattern?
"never ever ever used to load directly" - you seem to know what you are talking about, but I am bot sure why? I am trying to move to pure OO paradigm, so I said OK, I will make all top level controllers as instances of a class.
Because your class is your blueprint. If you create a new invention you'd rather sell the product than the blueprint. All your classes should be instantiated in one file: your index.php. You bootstrap some prework and then classes do the work and even output your page.
OK. this is what I am doing now in index.php
