Recently I've been building a little project
that pulls data from Google Analytics and shows your web statistics in a
simple form. One thing I wanted to do was show the data for a quarter,
but graphing by day is too chaotic and graphing by month only gives
three points, so I wanted to graph by week. This was fine but the data
returned by Analytics only gives me the week numbers, and since this
project is aimed at demystifying web stats for normal people, it really
needs normal dates on it!
I found that the DateTime
extension has a method setISODate()
which accepts the year and week number, and makes a date you can then use as normal.
$week_start = new
You can also do this the other way around; if you have a date in PHP, there's the 'W' flag for date()
which will return you the week number - very handy!
