Tutorial Details:

PHP Tutorials
Before reading this tutorial, if you haven't already done so, it would be a good idea to read the writing to a file tutorial , as this one is basically a follow-on from it.
As always, start with the Now we define the file we are going to get the data from.
$file = file("data.db");
Next, we flip the data in the file around, so the latest addition to the file is displayed first, using the array_reverse() function :)
$file = array_reverse($file);
Then we use a foreach() loop to take the data from out data.db file, identify it and display each entry.
foreach($file as $key => $val) {
echo "$val";
}
Finally, end the code up with the ?> thingie.
?>
As I always do for the lazy ones out there, here is the complete code.
$file = file("data.db");
$file = array_reverse($file);
foreach($file as $key => $val) {
echo "$val";
}
?>
