The best way to troubleshoot/debug your PHP code for WordPress is to use the XDEBUG debugger for PHP coupled with an IDE/editor that can leverage XDEBUG.
By far my favorite IDE for PHP/XDEBUG is PhpStorm (best money I have ever spent), but you can use for free on the bleeding edge with their EAP (Early Access Program). You can also use the free VSCode with XDEBUG.
Here is a great video showing what it looks like to use XDEBUG & PhpStorm. You can start at the 18:00
point because everything before that is talking and slides.
You will also need a local development setup that supports XDEBUG. Several years ago I was frustrated with how difficult it was to get XDEBUG configured correctly so I had my team develop WPLib Box which pre-configures XDEBUG and thus makes using XDEBUG trivally easy. You can download WPLib Box from GitHub, use for free, and get help via our Slack.
I like to say using PhpStorm/XDEBUG/WPlib Box gives me WordPress superpowers. How else do you think I answered all the questions here at WPSE that I have? :-)
That said, there are also other local development solutions such as VVV, Trellis, Chassis, Desktop Server, MAMP, DevilBox, LaraDock, Kalabox, Kusanagi and others you might try. But I am not sure how difficult it is to set up XDEBUG to work with any of these others anymore and I know firsthand XDEBUG works without any fuss when using WPLib Box.
Hope this helps.

Just start with the following definitions in your config.php file:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('SCRIPT_DEBUG', true);
define('SAVEQUERIES', true);
The first one sets your system into debug mode, the second one writes every notice into a log file saved into your wp-content
directory. Script debug enables WordPress to use the uncompressed CSS and JS files (Maybe also interesting for writing Plugins). And Savequeries writes HTML-Comments at the bottom of the rendered HTML Output and will be used by Plugins I suggest you next.
See the WordPress Plugin Directory for Debug Bar and extensions. There are a lot and there's a great chance that some of them are providing exactly what you need.
If nothing helps you can write everytime
print_r( $var );
die();
and look into the HTML sourcecode.

Unfortunately there isn't really a standard developer logging API in WordPress. If you want to output your own data to a debug file (to prevent "headers already sent" errors) then you can simply use the standard PHP error_log
function. Something simple like this will record the variable $data
to the file debug.log
in your plugins directory:
$debugline = '['.date('y m d H:i:s', time()).'] '.print_r($data,true);
$debugfilepath = dirname(__FILE__).'/debug.log';
error_log($debugline, 3, $debugfilepath);
