Solution:
a 500 is a code error, or a server system error.
you can several things you can do to debug:
- make sure you have full error reporting on in your php.ini (or at the top of the script)
- try a simpler bit of code to make sure its not the server throwing the error.
- use xdebug to step through the code until you find where its failing. Then use a try/catch to try to find out what the error actually was.
- look in the server logs if you have access to them.
- write proper unit tests (you do write tests yes?) for the sections of code you are using. Often its easier to isolate a problem with a unit test than it is when that code is part of a much larger application.
- use echo’s and var_dumps to try to see where the code is falling over.
full error reporting. Put this at the top of your script if you dont have access to php.ini:
error_reporting(E_ALL);
