PHP upload Excel Export pdf~ Rookie for advice, big God pointing

Pdfphpexcel

Bothered me for three weeks needs: Online Excel to PDF.
The need is to upload Excel after php to PDF, I opened the use of Phpexcel, upload and then use tcpdf generation, but phpexcel cannot, or can not find the function to get column width and row height. It then calls the Tcpdf class library output directly with Phpexcel, but generates garbled--.
The environment currently in use is Php5.4+linux+tengine
Now there are a few questions that you would like to ask the great gods:
1.phpexcel How to get column widths and row heights
2. How to generate a PDF without garbled characters
3. If the content of Excel is too much how to move to the next page

But if there is any other way to do it, let me know.
