$fpLoc = ftell($this->fp);

$data = $this->fgetcsv();

fseek($this->fp, $fpLoc);

return (is_array($data));

}

function next() {

$this->currentLine++;

//Bump the file pointer to the next line

fgets($this->fp);

}

function rewind() {

$this->currentLine = 0;

//Reset the file pointer

fseek($this->fp, 0);

//Skip the column headers

fgets($this->fp);

}

function seek($line) {

$this->rewind();

while($this->currentLine < $line && !$this->eof()) {

$this->currentLine++;

fgets($this->fp);

}

}

}
