PHP Include

This lesson is part of PHP · All levels

Summary

The include feature allows you to insert the contents of other files into the script, so the same part does not need to be rewritten. It's useful for header, footer, or shared configuration. This lesson also distinguishes include from require as well as the advantages of include_once and require_once.

Key points

Include inserting other file contents while the script is running
Require the same function, but stop the script when the file is not found
Include_once/require_once prevents the same file from being loaded more than once
Header/footer separation makes it easy to maintain multiple pages
