Simple tree

Complex tree

Basic usage

1. Require this library to your PHP project:

composer require markfullmer/dependency_tree

2. Ensure the library is autoloaded in your PHP file:

use markfullmer\DependencyTree;

3. Copy or reference the d3.dependencyTree.js file from this library into your project and load it into a web page, along with the underlying D3JS API library.

<script src='https://d3js.org/d3.v4.min.js'></script>
<script src='./js/d3.dependencyTree.js'></script>

3. Supply the contents of composer.json and composer.lock files as arguments and generate the tree. (Change the third parameter to TRUE to print version information.)

  $data = DependencyTree::generateTree($root, $lock, FALSE);

4. Render the resulting data via Javascript, supplying the data and an HTML target ID.

  echo '
    <script>
      dependencyTree('. $data .');
    </script>
  ';
