Using jqueryuploadify in php cannot upload video files

! Export htmlcode (img.ask.csdn.netupload201506031433331378_675203.png )! When the background program (img.ask.csdn.netupload201506031433331423_507447.png) goes crazy, upload the same code, print the image, and there is no data problem! Upload (img.ask.csdn.netupload201506031433331414_906163.jpg) but I will upload the video file phpjquery when I change it to a video.

I'm so crazy that I uploaded the same code and printed the image, so there's no problem with the data.
But I change it to a video.

Hope to answer your question
