Now that some data exists, it's time to make sense of it in the form of
|
|
a graph. The inclued extension includes a PHP file named
|
|
<filename>gengraph.php</filename> that creates a dot file that
|
|
requires the <link xlink:href="&url.graphviz;">graphviz</link> library.
|
|
However, this form is not required.

This example creates an image named inclued.png that
|
|
shows the inclued data.

When using the <link linkend="ini.inclued.dumpdir">inclued.dumpdir</link>

directive, files (include clues) are dumped with every request. Here's one

way to list those files, and <function>unserialize</function> them.
