- [分享]碰上 error: Some data has already been output, can't send PDF file
- 關於使用 tcpdf 時，有人會碰上『error: Some data has already been output, can't send PDF file 』！
這東西應該不是 tcpdf 的 bug，基本上他是因為你之前已經有輸出過了，導致不能正常的輸出
而在部份使用 tcpdf 的系統上（如：vTiger）也會碰上類似的問題
照理說，應該是可以重複輸出的啊！？
至少冷日看 tcpdf 給的 sample 都沒有改名或怎樣就可以直接不斷地一直重複輸出！
可後來冷日看到了解決方案：『ob_end_clean』！
也就是說在你開始輸出 pdf 之前加上
就可以解決了，冷日也就先這樣用囉！
希望可以幫到也有類似困擾的朋友。

- Every new campaign or marketing piece that you develop needs to be tested for effectiveness. Traffic Geyser is software program that provides an interface which allows uploading a relevant video document, including information to be passed on to the video sharing site, and submit the document to a number of video sharing sites. The use of images and sound is able to elicit feeling and better understanding of the idea. The newest Flips now have HD technology to improve the look of your video captures. You - Tube is one of the best places to market your business because you can illustrate what you are saying.
