<?php
#
# retrieve total count of weeks in a year
#
# param: (int) $year the year in which you wanna get the week count; if not int (for example from
date('Y') it is automatically casted
#
# --- NOTE:
# seen a lot of stuff around but nothing as fast;
# mktime() is a very performant operation and the loop
# is executed max 13 times
#

# see: http://www.php.net/mktime
# see: http://www.php.net/intval
