To chain a static and a public method through class name, for example:
className::staticMethod()->publicMethod()
The instance of the className must be returned in the staticMethod, using "return new self" .
- Code example:
<?php
class clsShow {
  public static $url;

  public static function setData(){
    self::$url = 'http://coursesweb.net/';
    return new self;
  }

  public function show(){
    echo self::$url;
  }
}

// accessing show() method after setData()
clsShow::setData()->show();             // http://coursesweb.net/
