Add sub-element to function list in Notepad++

When I code php, I use Notepad++ with nppFTP on the left side of my screen, and the browser on the right side, to quickly see the changes.

On bigger projects, I can easily surpass 1100 rows of code for a single php file of many. Each php file has just one class with a few functions, but as the code grow, the amount of rows for a function get substantially larger too. This means I am scrolling through my code a lot when I work on different sections at a time because one part of the code may rely on another part of the code.

I found out that I can display the function list, which will show me all the functions in my class and a double-click allows me to instantly jump to the function. This is already great, but given that the functions themselves may easily have 300 lines of code, it is still quite a bit of scrolling once I jump to a function.

I found out that I can simply insert the following code in my script to add a fake function that shows up in the function list:

    ?>< ?

but this only works if this does not break the code. For example, I have a function that processes form posts, and every section is inside a switch() { … }

So my function that processes all Post events, separate them based on a switch. This makes the code fast and readable, but inserting a fake function breaks the code unless I place the fake function inside the case block. This is a work around, but it would be so much better if I could somehow put the if’s and switches inside the function list.

Is there a way I can add sub items to the function list for php files?
