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
