的订单的定义目录索引的文件还确定其优先级。

The order of the defined 'directory index' files also determine their priority.

在您的情况，如果双方的 index.html的和的index.php 是present， Apache会挑 index.html的。

In your situation, if both an index.html and a index.php are present, Apache will pick the index.html.

要改变这种情况，改变目录索引文件的顺序;

To change this, change the order of the 'directory index' files;

DirectoryIndex index.php index.html
