Separating HTML from PHP

The last approach I want to discuss involves using the include and require
functions. As you may recall from Chapter 8, "I/O Functions," these functions
include a file in the PHP code. The file is considered to be a PHP file, regardless of the
extension on the name. If PHP code appears in the included file, it is surrounded in <?
and ?> tags. You may want to turn back to the functional reference to refresh yourself on
the differences between include and require , but they aren't particularly important
to this discussion.

Certain chunks of HTML must appear on every well-formed page. Additionally you may
develop repeating elements such as a company logo. Rather than write them into every
page, you may choose to put them into a file and dynamically include them. Listing
20.7 contains HTML you might include at the top of every page on a site. In Listing
20.8 are two lines to close a page. Listing 20.10 wraps the content in Listing 20.9
with the opening and closing code to form a complete page.
