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 ;
}
 ?>

以上例程的输出类似于：

PATH: /tmp/inclued
Inclued file: inclued.56521.1
 -- filename: /Users/philip/test.php
 -- number of includes: 1Inclued file: inclued.56563.1
 -- filename: /tmp/none.php
 -- number of includes: 0Inclued file: inclued.56636.1
 -- filename: /tmp/three.php
 -- number of includes: 3

If you install the module and execute it via CLI it will not produce any errors when not enabled. It took me quite a bit of time until I realised that by default the module is disabled, http://www.php.net/manual/en/inclued.configuration.php.

Note that inclued does not work correctly when xdebug is enabled (the includes array remains empty; consequently, graphing the classes works but graphing the files does not). Bug report: https://bugs.php.net/bug.php?id=59419

The new gengraph.php has ? -t ? parameter set to ? includes ? by default. Don't forget to specify it to ? classes ? for most of all projects.

Since PHP 5.3, namespace operators are stripped by Graphiz when the graph is generated. Add the following tips to escape namespace operators:

<?php // Around line 254 else { $filemap = array(); foreach($data["classes"] as $k => $v) { $class = $v; // Here is the tip to remove namespaces $class['name'] = str_replace('\\', '\\\\', $class['name']); $class['mangled_name'] = str_replace('\\', '\\\\', $class['mangled_name']); // ... ?>

By the way, if you are looking for an easy way to use inclued, take a look at my library: http://www.eexit.net/projects/inclued.html
