PrePHP

If you're looking for a tool that can render static PHP sites to regular HTML sites, then PrePHP might be just what you need. By doing this, your server won't need to do any additional rendering, which can help reduce the amount of CPU load placed on it. And, because it eliminates the need for PHP altogether, you can keep things running smoothly without worrying about whether or not this programming language is supported.

Of course, there are some limitations to be aware of. For example, PrePHP can only render a maximum of five files per session, so you'll need to plan accordingly if you have a large number of files that need to be rendered. However, depending on your needs, this particular limitation may not be a big deal, given all the other benefits that PrePHP has to offer. Ultimately, whether or not this software is right for you will depend on your specific website and server setup, as well as your budget and overall goals.
