    Example that implements inclued into an
    application

    This example demonstrates the process of
    implementing inclued into an existing application, and viewing the
    results.

    Example #1 Getting the data within the PHP application
    itself (function)

    <?php
    // File to store the inclued information
    $fp = fopen('/tmp/wp.ser', 'w');
    if (    $fp) {
            $clue = inclued_get_data();
        if (    $clue) {
                fwrite($fp, serialize($clue));
        }
            fclose($fp);
    }
    ?>

    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 gengraph.php that creates a
    dot file that requires the » graphviz library. However,
    this form is not required.

    Example #2 Example use of gengraph.php

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

    # First, create the dot file
$ php gengraph.php -i /tmp/wp.ser -o wp.dot

# Next, create the image
$ dot -Tpng -o inclued.png wp.dot

    Example #3 Listing data via inclued dumps
    (configuration)

    When using the inclued.dumpdir directive, files (include clues) are
    dumped with every request. Here’s one way to list those files, and
    unserialize() them.

    <?php
    $path     = ini_get('inclued.dumpdir');
    if (    $path && is_dir($path)) {

        echo "Path: $path", PHP_EOL;

        $inclues = new GlobIterator($path . DIRECTORY_SEPARATOR . 'inclued*');

        if ($inclues->count() === 0) {
            echo     'No clues today', PHP_EOL;
            exit;
        }

        foreach ($inclues as $inclue) {

            echo 'Inclued file: ', $inclue->getFilename(), PHP_EOL;

            $data = file_get_contents($inclue->getPathname());
            if (    $data) {
                    $inc = unserialize($data);
                echo     ' -- filename: ', $inc['request']['SCRIPT_FILENAME'], PHP_EOL;
                echo     ' -- number of includes: ', count($inc['includes']), PHP_EOL;
            }
            echo     PHP_EOL;
        }
    } else {
        echo     'I am totally clueless today.', PHP_EOL;
    }
    ?>

    The above example will output something similar to:

    PATH: /tmp/inclued
Inclued file: inclued.56521.1
 -- filename: /Users/philip/test.php
 -- number of includes: 1

Inclued file: inclued.56563.1
 -- filename: /tmp/none.php
 -- number of includes: 0

Inclued file: inclued.56636.1
 -- filename: /tmp/three.php
 -- number of includes: 3
