This is a project I'm designing and coding. Far from done as of this post, but I hope to have it reasonably functional by July 2012.

Python: Error Handling

import traceback
def formatExceptionInfo(maxTBlevel=5):
         cla, exc, trbk = sys.exc_info()
         excName = cla.__name__
         try:
             excArgs = exc.__dict__["args"]
         except KeyError:
             excArgs = ""
         excTb = traceback.format_tb(trbk, maxTBlevel)
         return (excName, excArgs, excTb)

try:
         x = x + 1
except:
         print formatExceptionInfo()

Create an associative array in PHP

Some of you may dislike the distraction of a full set of working code with core lesson of associative arrays buried in it. Their are plenty of minimalist examples on the web, and when I wanted an example they were too minimalist. Core code for reference is in this color scheme.
