PHP 5 has some handy new functions but two that really stand out are date_sunrise and date_sunset ..... I can see some potential uses such as a weather channel, or a counter for a competition or for religious prayers but asides from that, are there are any other important uses that had to be implemented as a function ?

what I also dont like about it is the type of input data it needs to return an answer

mixed date_sunrise ( int timestamp [, int format [, float latitude [, float longitude [, float zenith [, float gmt_offset]]]]] )

other than that little "rant" I think PHP 5 is definitely a major step from 4.0
