Debugging PHP
In MediaWiki there is a profiler that can be set, see MW:How to debug.
Debuggers generally use a W:Stack trace. This can be approximated by using print and die statements in sections of code.
The combination of print_r and func_get_args allows you to return an array of args that a function was called with;
print_r(func_get_args());
PHP errors
To see PHP errors, add this to the very top of LocalSettings.php:
error_reporting(E_ALL);
ini_set("display_errors", 1);
