How do I generate UML diagram based on existing classes in PHP?
There's also the PHP UML tool available from pear.
PHP_UML:
Install it on the command line via:
$ pear install pear/php_uml
(This used to be $ pear install pear/php_uml-alpha
but the package has since gone stable.)
Generate your xmi:
$ phpuml -o project.xmi
