访问本地项目,php不被解析,出现文件下载

Question

我使用的是nginx的webserver,目前访问php文件不被解析,全部变为下载,之前改过php相关的配置文件,以为是因为没有修改正确,但是刚刚重装了php,仍然出现php文件被下载的问题,所以怀疑可能是nginx配置不正确,但是网上搜出来的情况都不尽相同,所以无法确定自己哪里写的不对,请大家帮忙看一下

Answer 1

    default_type  application/octet-stream; 
    #指定默认类型为二进制流，也就是当文件类型未 定义时使用这种方式，例如在没有配置PHP环境时，Nginx是不予解析的，此时，用浏览器访问PHP文件就会出现下载窗口

改成默认配置

    default_type text/html;
