Who knows what this code means? How can we achieve a normal page?

Reply to discussion (solution)

I clicked on each file in the directory to display this code. Others are not displayed.

It should be a cache.

It should be a cache.

This is displayed on every page. Will it be encrypted.

The meaning of the code itself is to create a cache object
But the code you posted is disabled.

Every page appears. Obviously, this code is included by other programs as an independent file.
But this program is written in the short Mark format, and you have not enabled the short Mark switch.
As a result, the program is directly output as html, and the program starts Obj = ex_memcache ();
It is marked by the browser and cannot be seen (right-click it and you will see the source code of the webpage)

This is the memcached cache service.

Correct. I thought it was encrypted.
