    Alot of people have asked for VERY simple FTP functionality with PHP, so here it is.
    This class was designed with very simplistic transfers in mind. You simple create the class,
    get/send a file and then 'kill()' the object. It's that simple. I you find it useful.
    
    Example:
    
    //Get a file
        require("class.ftp.php");
        $f=new PHP_FTP('ftp.somesite.com', 'username', 'password');
        $f->get('html/test.txt', 'c:/php/ftp/blah.txt'); //yes, tested on Windows
        $f->kill();
            
    //Send a file
        require("class.ftp.php");
        $f=new PHP_FTP('ftp.somesite.com', 'username', 'password');
        $f->send('c:/php/ftp/blah.txt', 'html/test.txt'); //yes, tested on Windows
        $f->kill();
     
     //how to test for completion
        if(!$f->send('c:/php/ftp/blah.txt', 'html/test.txt')){
            echo "File sent successfully!";
        }else{
            echo "Error sending file.";
        }
     
     Notes:
        Remember to have all permissions set to their appropriate settings before using
            this class
