Is it Possible to Pair a Few Dynamic (PHP) Pages with Jekyll Generated Site?



I am considering using Jekyll for a project. However, I am not sure it will work for my scenario. While the vast majority of the website is well-suited to static HTML, I do have a few forms that are sent through email (using PHP). My question is, is there anyway to use a Jekyll generated site in harmony with PHP scripts? I have my owner server running PHP so that is not the issue, the question if this can be used with Jekyll generated sites, particularly in regards to routing/navigation?
