[limesurvey-developers] Drop PHP4 support for 1.85

[Carsten S. <car...@go...>]

Hello!

Today I found out that one of the libraries in 1.85 (daterparser.php) is 
PHP5 only. At the time I put it in I though it would be PHP4 compatible 
because it was marked as such. That after more than one week of 1.85RC 
being released nobody really complained is a sign for me to move forward 
on this and I would like to make 1.85 PHP5 only.

Here a few argements for PHP5 and up only:

- Most open source projects dropped  PHP4 support more than a year ago.
- PHP6 is around the corner - and I would not want to provide support 
for 3 different PHP versions.
- Dropping PHP4 support would make the code alot more slim in some cases 
- being more performant and we can drop old compatibility functions.
- PHP5 provides a good number of worthy datetime functions which would 
be very hard to implement in PHP4 - especially with the rising number of 
datetime problems we are approaching with 1.85RC2.

It would be great to be able to handle easily different datetime formats 
in the survey and with PHP5 I would be willing to implement these 
settings for the administration and client side on short notice (in this 
case I would break my own feature freeze).

Anyone of you still using PHP4?

Comments please...
