PowerPoint templates silently write a template engine

Engine files

Copy the Code code as follows:

* The OOP class template engine developed silently based on the Discuz template engine can support template caching and generate hash MD5 values. By the hash value to determine whether the template is modified, if modified to regenerate the cache file, if not modified, directly call the cache file.

How are you doing

Thank you

This template is silently written this afternoon, write a relatively hasty, perhaps there is a loophole, this version is only beta, and I will gradually improve, first sent out, as a forward-looking.

The above describes the PowerPoint template silently wrote a template engine, including the content of the PowerPoint template, I hope the PHP tutorial interested in a friend helpful.
