He makes it clear that papers/1375680721.pdf does not exist because the file exists.

If the file does not exist, you cannot pass this judgment.

Check whether the file permission is correct. set papers/1375680721.133 to 777.

Check whether the file permission is correct. setting the papers/1375680721.133 permission to 777 is not a Permission Problem. I suspect there is a problem with imagemagick. I opened imagemagick and threw the PDF file in, prompting

If (! File_exists ($ PDF) only checks whether the file pointed to by $ PDF exists.
The statement you open in pdf is $ IM-> readImage ($ PDF. "[". $ page. "]");
Obviously, $ PDF and $ PDF. "[". $ page. "]" are not the same thing.
Where does your writing look like this? Please provide the source!
I have not found this method in the searched code.
If you say $ PDF. "[". $ page. "]" indicates the $ page of $ PDF. if $ page does not exist, should we report an error?

I have no imagick environment and cannot test it. Just according to common sense

Run in Windows, you also need to install a software ghostscript;: http://downloads.ghostscript.com/public/gs904w32.exe; wish you success.
