[FX.php List] Snippet: Displaying Error Code Messages

[Jonathan Schwartz]

Well...yes.  For a beginner, arrays are some unknown (Don't Ask, 
Don't Tell) entity that work mysteriously behind the scenes.  Only at 
the point when a developer is forced to reckon with them, do their 
true power become apparent.  Then you don't know how you managed 
without them.
