Use PHP_UML to generate a UML diagram of the code

When reading other people's code and without detailed documentation, how to quickly see the entire code structure (class structure) becomes a real problem. today I will introduce a method for automatically generating UML diagrams.

Today I will introduce a method for automatically generating UML diagrams.

Suppose that I have a project folder: laruence, which has a file Root. php (in fact, no matter how many levels of directories, multiple files ).

 
 

  
  
  
  
  
abstract class Root {
  
  
    private $instance;
  
  
    abstract public function Hi();
  
  
}
  
  
 
  
  
interface Intro {
  
  
    public function Say();
  
  
}
  
  
 
  
  
class Sub extends Root implements Intro {
  
  
    private $instance;
  
  
    public function Say() {
  
  
        echo "I am Laruence";
  
  
    }
  
  
    public function Hi() {
  
  
        echo "Hello!";
  
  
    }
  
  
}
  
  
?>
 
 

First, we need to use PHP_UML (PHP_UML) to generate XMI based on the code.

The usage is relatively simple. after installing PHP_UML, run:

 
 

  
  
 phpuml laruence/ -o laruence.xmi -n laruence -f xmi --pure-object --no-deployment-view --no-component-view --no-docblock
 
 

You will get a laruence. xmi file. you can learn the specific parameters of phpuml through phpuml-help.

With xmi, how can we convert it into a UML diagram?

Visio2007 does not support importing XMI. I found another tool: Altova Umodel, which supports conversion from XMI to UML diagrams and needs to be registered, however, a 30-day license is provided (if you have a better replacement solution, please add it ).

After Umodel imports laruence. xmi, a UML diagram is generated and the following PNG is obtained:

Is it convenient?

In addition, PHP_UML can also generate html format, which is also good for a doc gen tool. you can also generate php files through xmi.
