__call and __callStatic not working properly or writing incorrectly

<?php
    class Statics {

        private static $keyword;

        public static function __callStatic($name,$args){
            self::$keyword = "google";
        }
        public static function TellMe(){
            echo self::$keyword;
        }
    }

    Statics::TellMe();

This is a simple breakdown I tried using __construct but the way I write the code Statics::TellMe(); I would need to write new for the __construct to work. And my private static variable keyword does not get written without it being called any ideas as to why this is not working??

IDE Not Working Example

    private static $pathname;
    public function __construct($dir = "")
    {
        set_include_path(dirname($_SERVER["DOCUMENT_ROOT"]));
        if($dir !== "") {
            $dir = "/".$dir;
        }
        self::$pathname = $dir.".htaccess"; 
        if( file_exists(self::$pathname) ) {
            self::$htaccess = file_get_contents($dir.".htaccess",true);
            self::$htaccess_array = explode("\n",self::$htaccess);
        }
    }

The self::$patname is not getting assigned because I am not doing $key = new Key(); so I need a way to do it if I just do Key::get() or anything like that.

You do have a misunderstanding in the way __callStatic is working. The magic method __callStatic will act like a fallback method when a static method is unknow to the class.

class Statics {

    private static $keyword;

    public static function __callStatic($name,$args){
        return 'I am '.$name.' and I am called with the arguments : '.implode(','$args); 
    }
    public static function TellMe(){
        return 'I am TellMe';
    }
}

echo Statics::TellMe(); // print I am TellMe
echo Statics::TellThem(); // print I am TellThem and I am called with the arguments : 
echo Statics::TellEveryOne('I','love','them'); // print I am TellEveryOne and I am called with the arguments : I, love, them

So in your case what you could do is :

class Statics {

    private static $keyword;

    public static function __callStatic($name,$args){
        self::$keyword = "google";
        return self::$keyword;
    }
}

echo Statics::TellMe();

As per your edit :

class Statics{
    private static $pathname;
    private static $dir;

    public function getPathName($dir = "")
    // OR public function getPathName($dir = null) 
    {
        if($dir !== self::$dir || self::$pathname === ''){
        // OR if($dir !== null || self::$pathname === ''){ -> this way if you do getPathName() a second time, you don't have to pass the param $dir again
            self::$dir = $dir;
            set_include_path(dirname($_SERVER["DOCUMENT_ROOT"]));
            if($dir !== "") {
                $dir = "/".$dir;
            }
            self::$pathname = $dir.".htaccess"; 
            if( file_exists(self::$pathname) ) {
                self::$htaccess = file_get_contents($dir.".htaccess",true);
                self::$htaccess_array = explode("\n",self::$htaccess);
            }
        }
        return self::$pathname;
    }
}

echo Statics::getPathName('some');
