That'd be pretty confusing. How about this?

$fw = new FifoWriter();
$fw->open('foo.txt');

$fw->write('Lorem ipsum dolor sit amet');
$fw->write('Consectetur adipisicing elit');

$fw->close();

The code would roughly look like this:

class FifoWriter{
private $fp;

public function open($file){
$fp = fopen($file, 'w');
if($fp){
$this->fp = $fp;
}else{
throw new Exception('Could not open file: ' . $file);
}
}

public function open($file){
$fp = fopen($file, 'w');
if($fp){
$this->fp = $fp;
}else{
throw new Exception('Could not open file: ' . $file);
}
}

public function write($data){
if( !fwrite($this->fp, $data) ){
throw new Exception('Could not write data');
}
}

public function close($file){
fclose($this->fp);
}
}
