尝试OutPut时出现FPDF错误

I am getting FPDF Error while trying to OutPut

    require('cons.php');  
    $fpd = new fpdfx();
    $fpd->AddPage();
    $fpd->SetFont('Arial','B',16);

FPDF错误:已经输出了一些数据，无法发送PDF文件

推荐答案

尝试注释掉$ fpd-> Output();并查看是否有任何通知或其他发送到输出的数据.

Try to comment out the $fpd->Output(); and see if you got any notice or other data sent sent to the output.

如果没有，请深入到Output()方法并使用die();直到找到什么数据出来！

If not, dig into the Output() method and use die(); until you find what puts some data out!
