The $this variable you're using in your code is just a variable. ie

function DoEvents($this){
   echo $this;
}
DoEvents('string'); //will echo string

Unless your function is inside a class, $this would refer to the current class. ex:

//http://www.php.net/manual/en/language.oop5.basic.php
class SimpleClass
{
    // property declaration
    public $var = 'a default value';

    // method declaration
    public function displayVar() {
        echo $this->var;
    }
}
