If you use Adobe Dreamweaver and you program a lot in PHP, you find out that you did not offer the functions, classes, ... present in the files included with "include" or "require".
To remedy this problem, Adobe had posted a video in English on its old website "Adobe TV". This tutorial is based on the official video.

Compatibility: CS5 and higher
 
To begin, make sure you are well selected your site in the "File" then go to the menu Site -> Indicators codes specific to the site.

Besides "file(s)", click the + icon.

Then click the folder icon.

Select the root directory of your website.

Then check the "Recursive" checkbox is checked and click "Add".

Make sure the boxes "Analyze folder" and "recursive" are checked property and click "OK".

The "Save settings structure" will then be displayed. Indicate, for example the name of your website and click on "Save".

As you can see from this example, Dreamweaver now display all the functions and methods present in the included files.
It also tells you the name of the file and (if applicable) the name of the class in which these methods can be found.
