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 = 'https://coursesweb.net/';
return new self;
}
public function show(){
echo self::$url;
}
}
// accessing show() method after setData()
clsShow::setData()->show(); // https://coursesweb.net/
