try using the class like this:

CLASS db{

    public static function select(){
        $arg = func_get_args();
        if(empty($arg)):
            $selectClust = "*";
        else:
            $selectClust = implode(',',$arg);
        endif;
        
    return "SELECT ".$selectClust;
    }
    
    public static function from(nsqlQuery $e){
        $arg = func_get_args();
        return "FROM ".rtrim(implode(' ',$arg));
    }

} 

then this:

<?php

db::select()->from('table');

?>

should work correctly.

to use a class like db::somthing
you need to either...
1) make the class static (like i have here)
2) or you need to make a constructor thats calls a function inside the class, that will make the class a single call each time its called.
