…If you think this task simply involves…calculating mean and median averages, think again.…Calculating the averages requires only a few lines of code and you're done.…Now this task goes much deeper.…Maybe not as deep as Lake Pend Oreille, but deep enough.…Let's take a look at the way the Pend…Oreille raw data is organized by going to the website.…Then clicking the raw data link on the main…page and it's deep more weather data that we want.…And the environmental data for 2001 through to…2010 is stored in these large text files.…
They range in size from about one and half megabytes.…To this one for 2008, which is nearly seven megabytes.…But if we look at the date for 2010, we…can see that it comes to an end in late May.…Thereafter, each measurement is in a separate…file that contains just one day's data.…So if we open this 2014 folder, we can see…inside the series of other folders one for each day.…And if we just open one at random we can see there…are 11 files in there one for each different type of measurement.…
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
