Ajax compatibility issues in linux and windows (system error:-1072896658)

Ajax compatibility issues in linux and windows (system error:-1072896658) -- Linux Enterprise Application-Linux server application information. For details, see the following. I developed it on the windows platform. Since the server is a linux system, after the code is uploaded, ajax all experienced the "system error:-1072896658" error, which was later known, it turns out to be a coding problem.

Add the header ('content-Type: text/plain; charset = UTF-8 ') to the PHP file on the ajax server. This line of code is OK.
