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);
	}
}
