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:
1 2 3
// 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.pngThe result will look like this:
Inside a Symfony application, you can dump the dot file with the
workflow:dump command:
1
$ php bin/console workflow:dump name | dot -Tsvg -o graph.svgNote
The dot command is part of Graphviz. You can download it and read
more about it on Graphviz.org.
