If you create a text file much like this:
20061101,Apple,Normandy
20061102,Orange,Seville
20061103,Pineapple,the Azores
20061104,Coconut,Fiji
You should be able to pull that information into PHP very easily using the
file() function; find out today's date using date(); then loop through
each line of the file comparing the first few characters of the file with
today's date, something like this:
$today = date('Ymd');
$lines = file('data.txt');
$info = FALSE;
while (!$info)
{
$thisline = array_pop($lines);
if ($today==substr($thisline,0,8))
$info = $thisline;
}
This will find you the relevent line and store it into a variable called
$info.
The rest is easy-peasy...
list($today,$fruit,$location) = explode(',', $info);
printf("Today's drink is %s juice from %s.", $fruit, $location);
