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 image of the workflow defined above:
1 2 3
// dump-graph.php
$dumper = new GraphvizDumper();
echo $dumper->dump($definition);1
$ php dump-graph.php | dot -Tpng -o graph.pngThe 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 -Tpng -o graph.pngNote
The dot command is part of Graphviz. You can download it and read
more about it on Graphviz.org.
