This script is created for you to be able to include 1 file in another file. The most common use for this script is to serve as a Header/Footer. This will include an entire file with just 1 simple command. NOTE: if you are trying to include a file in HTML you must have SSI enabled on your server. Most servers today have php installed for free so if you need this functionality, consider switching to another language.
