How to Dump Workflows¶

To help you debug your workflows, you can dump a representation of your workflow with the use of a DumperInterface. Use the GraphvizDumper to create a PNG or SVG image of the workflow defined above:

// dump-graph.php
$dumper = new GraphvizDumper();
echo $dumper->dump($definition);

1 2 3 4

$ php dump-graph.php | dot -Tsvg -o graph.svg # run this command if you prefer PNG images: # $ php dump-graph.php | dot -Tpng -o graph.png

The result will look like this:

If you have configured your workflow with the Symfony framework, you may dump the dot file with the WorkflowDumpCommand:

1	$ php bin/console workflow:dump name | dot -Tsvg -o graph.svg

Note

The dot command is part of Graphviz. You can download it and read more about it on Graphviz.org.
