Is it different between two way to call a function in an other class?

I have a class

<?php
class Test{
    public function printword($word){
         echo $word;
    }
}
?>

And in another class, i call it.

<?php
//Included needed files !!!
$w = 'Hello';

//Way 1
$a = new Test;
$result = $a->printword($w);

//Way 2
$result = Test::printword($w);
?>

Is it different ?

And $a = new Test; or $a = new Test(); is right ?

Yes, it's different. if you declare a method static makes them accessible without needing an instantiation of the class.

class Test{
    public function printword($word){
        echo $word;
   }
}

//Call printword method
$a= new Test();
$a->printword('Words to print');

Static Method:

class Test{
    public static function printword($word){
        echo $word;
   }
}

//Do not need to instantiation Test class
Test::printword('Words to print');

See the documentation.
