GraphYEd extends graphp/graphml for supporting yEd file format for GraphML.

It provides access to the vertices (or nodes) and edges labels :

• $vertex->getAttribute('labels')
• $edge->getAttribute('labels')

Please refer to GraPHP library for more details on how to manipulate graphs.

The recommended way to install this library is through Composer.

$ composer require edno/graphyed

The method getAttribute('labels') will return an array of type string.

<?php

$loader = new \edno\GraphYEd\Loader();

$graphml = file_get_contents('mygraph.graphml');

$graph = $loader->loadContents($graphml);

foreach($graph->getVertices() as $vertex) {
  print($vertex->getAttribute('labels')[0]);
}
