I recently finished a fairly large website project that I've been working on. But I have realized how time consuming it is to update it.
Because of this, I have decided to use the php "include" function so I can update the CSS, navigation, and footer once, and update the whole website. I created a test page to see if it would work correctly. It did, but the page took 3-4 seconds to load on a fast computer. Without using the PHP "include" function, the page usually takes about half a second to load on the same computer.
Is there a way to use the "include" function and still keep the loading time fast?
