Solved.
I modified XAMPP's php.ini file to point to the xdebug.so that homebrew installed,
zend_extension="/opt/homebrew/Cellar/php/8.2.3/pecl/20220829/xdebug.so"
Then, I restarted the XAMPP server and ran this in terminal
/Applications/XAMPP/xamppfiles/bin/php -v
Before the expected PHP info, there were some errors. Several times in the warnings it stated "...(mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')..."
Oops.. I swore I chose x86_64..
So, I ran the following in terminal:
pecl uninstall xdebug
Then,
arch -x86_64 sudo pecl install xdebug
Following that I again ran /Applications/XAMPP/xamppfiles/bin/php -v and, voila!

Homebrew has to be used in a consistent way: you can't use it to install an extension to a program installed by another way. If XAMPP is using its own set of paths and stuff, Homebrew can difficulty adapt to it: it's not made for that situation.
Why don't you change your "PHP executable" and "Configuration file" options to the homebrew ones?
Step 1: goto https://xdebug.org/wizard.php
step 2: copy and paste your phpinfo output to textarea which will be displayed on https://xdebug.org/wizard.php
step 3: click on analyze my phpinfo() output button, it will analyze your system and based on that it will give you suitable php_xdebug.dll file that you need to put at D:\xampp\php\ext folder
step 4: edit your php.ini file and add following line zend_extension = D:\xampp\php\ext\your-php_xdebug.dll
step 5: Restart Server

Recent XAMPP version(mine is v3.2.2) already had the file php_xdebug.dll in xampp\php\ext folder , so we don't need go to https://xdebug.org/wizard.php for downloading the file.
Just open the file xampp\php\php.ini, add the codes:
[xdebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
Restart the XAMPP, then you could see the xdebug is working by type php --version in CMD:

I have been trying for 2 days to get PHPStorm to work with XDebug and either XAMPP or Local and I just cannot seem to figure it out.
Here's what I would like to do.....
I have a WordPress site that needs some minimal changes to some API calls. I have no problem writing that code. I've written it in plugins and it's running fine. But I wrote that "blind" - as in I just wrote the code in a text editor and uploaded it and it works.
I want to be able to do more serious debugging with a tool like PHPStorm so I can step through the code on the site that I didn't write (and don't completely understand) to learn what it does and possibly fix some PHP errors that I see popping up.
I backed up the production site using UpdraftPlus, downloaded the backup files and restored the production site to a local dev site in XAMPP and I also did the same thing to a local dev site in Local.
Both sites work just like the production site (just a bit slower than the production site running on a Cloudways virtual server). The XAMPP site runs 2 to 6 times faster than the Local site, depending on what you are doing (uploading files or just surfing the site, etc.).
It is at that point that I am failing to do what I need to do. Here is what I need to be able to do....
Load either site into PHPStorm
Open a file in PHPStorm and set a breakpoint
Open a browser and go to the page/button/whatever that triggers the code
Have the code stop at the breakpoint in PHPStorm for inspection/changes
Be able to step through the code from the breakpoint forward, learning what the code is doing
I'd like to use PHPStorm for this, but getting it all set up is like some cruel joke. I've seen examples of people setting up CLI servers, actual servers, assigning PHP executables, etc. in YouTube video after video. Most of the videos are 2 to 10 years old and you might get half done or even 75% done when their UI no longer looks like yours and finding the settings they are tweaking is nigh impossible. Even if you find something that looks similar it's never exactly the same and there are more fields to fill out with no clue what goes in them.
Then there are several different ways that I've seen the php.ini files and Apache settings done. Which is right? Which is best? Who knows? Not me....that's for sure.
Worse yet is the lost feeling when I cannot figure out just how they know even the parts that I can follow along with. I cannot, for the life of me, find a simple "Step 1, Step 2, Step 3...." that is current and works to set this stuff up.
There doesn't seem to be an "Absolute Idiot's Guide to PHP Debugging with PHPStorm and XAMPP" - which is what I think I need at this point.
And it is odd to me that there is no checklist or walk-through plug-in in PHPStorm or VS Code that asks you questions and sets up the environment based on your answers. There isn't even a written checklist that is current and workable that I can find.
It isn't all the fault of the tools (if any at all) though.....I am a full time caregiver for my mother who has Parkinson's. When not doing that I try and care for our dog who has congestive heart failure. When I can get away from those duties I have to maintain the home. And then I need to work - something I try to do from home as much as humanly possible because there is nobody to stay with my mother (who has fallen on occasion and needs someone nearby). The only undisturbed time I have to study any of this is when they are asleep (and I should be sleeping). So it is entirely possible that I am just worn completely out and cannot see the forest for the trees.
Be that as it may, I still am desperate to get this job done. I have 3 weeks to do it and if I can't get this unholy trio of PHPStorm/VS Code, XAMPP/Local and Xdebug to somehow come together into something useful, I don't see how I will make that deadline.
It isn't for lack of looking that I haven't figured it out....I've watched/read over 70 videos/articles and so far they all fail to produce the desired result.
