Is it possible to create static classes in PHP like in C

Question

I'm trying to make a static class in PHP behave like a C# class, so,

• On the initial call to the class, the function Object() { [native code] } is immediately called.
• No instantiation is necessary.

Something like this:

static class Hello {
    private static $greeting = 'Hello';

    private __construct() {
        $greeting .= ' There!';
    }

    public static greet(){
        echo $greeting;
    }
}

Hello::greet(); // Hello There!

 Can someone please help me with this?

Although static classes are possible in PHP, they do not automatically execute the function Object() { [native code] } (if you attempt to call self:: construct(), an error will be returned).

As a result, you would need to develop an initialise() function and use it in each method:

<?php

class Hello
{
    private static $greeting = 'Hello';
    private static $initialized = false;

    private static function initialize()
    {
        if (self::$initialized)
            return;

        self::$greeting .= ' There!';
        self::$initialized = true;
    }

    public static function greet()
    {
        self::initialize();
        echo self::$greeting;
    }
}

Hello::greet(); // Hello There!


?>

I hope this helps you.
