Unless you are going to change the exception, you should only log at the level where you are going to handle the error and not rethrow it. Otherwise your log just has a bunch of "noise", 3 or more of the same message logged, once at each layer.
My best practice is:
1. Only try/catch in public methods (in genera... |
I guess it depends on where you want to store the text, if you need things like transactions etc.

There are various ways of computing quantiles when you give it a vector, and don't have a known CDF.

If you're required to log all exceptions, then it's a fantastic idea. That said, logging all exceptions without another reason isn't such a good idea. |

You can use relative paths...try **__FILE__**. This is a PHP constant which always returns the path/filename of the script it is in. So in soap.php you could do:

Some things to think about when choosing between these mechanisms are:

3. Do you want to read some of your

Keep in mind that TempData stores the form collection in session.
