Generate UML of PHP code

Dude, take a look at this BOUML , I have never used it but I think it can help.

You can use PHP_UML

• Allows you to generate UML / XMI files version 1.4, or 2.1
• Generate HTML documentation
• Can generate PHP code skeletons based on a UML / XMI file
• Can convert UML / XMI files from version 1.4 to 2.1

To install via the command line you need PEAR. If you do not have install and then run the terminal:

pear install pear/php_uml

To generate the terminal path, simply use

phpuml [INPUT] -n [PROJECT NAME] -o [OUTPUT LOCATION] -f [OUTPUT FORMAT]

In the following example, PHP_UML will go through all files in /var/www/foo and export the file /var/tmp/MyProject.xmi naming the project as MyProject.

phpuml /var/www/foo -n MyProject -o /var/tmp/

For more command check documentation

Another way to generate is to create use API creating a PHP script. For example:

// Seta o caminho padrão de inclusão de arquivo como sendo a pasta do PEAR
set_include_path( '/usr/lib/php/pear/' );
require_once __DIR__ . '/uml/UML.php';

$uml = new PHP_UML();   
// Define qual pasta ou arquivos serão parseados
$uml->setInput('/var/www/foo');
// Realiza o parser e seta o nome do projeto como MyProject
$uml->parse('MyProject');
// Ignora alguns arquivos que contenha um padrão de nome
$uml->setIgnorePatterns('.svn');
$uml->export('xmi', '/var/tmp/');
