A Working Example
In this section, we use some of the techniques described so far to develop a simple, complete PHP script. The script doesn't process input from the user, so we leave some of the best features of PHP as a web scripting language for discussion in later chapters.
Our example is a script that produces a web page containing the times tables. Our aim is to output the 1-12 times tables. The first table is shown in Figure 2-2 as rendered by a Mozilla browser.

The completed PHP script and HTML to produce the times tables are
shown in Example 2-4. The
first ten lines are the HTML markup that produces the <head> components and the <h1>The Times Tables</h1> heading
at the top of the web page. Similarly, the last two lines are HTML that
finishes the document: </body>
and </html>.
Between the two HTML fragments that start and end the document is
a PHP script to produce the times-table content and its associated HTML.
The script begins with the PHP open tag <?php and finishes with the close tag
?>.
