Combining PHP and Webflow on a custom site

I have a PHP driven site I’d like to update with some Webflow content. The thing is, it’s a VERY interactive site, with a lot of PHP driven parts.

So my current technique is to download my Webflow site, and for pages I want to use, I open them in a text editor, replace placeholder strings with strings that the PHP side will identify as keys, and then I load and display that page as a template, which runs through the PHP scripts before being served.

Is there a better way, or something I’m missing? This technique works, just curious if I’m missing something obvious.

Thanks!
