Using Multiple Pages for Navigation - Recap
(Page 2 of 5 )
Let's start by taking a look at notepad's final script:
<?php
// if a page isn't defined, we're on page one
if($page <= 0)
{
$page = 1;
}
// create an array of data
$myArray = file("data.txt");
// reverse the order of the data
$myArray = array_reverse($myArray);
// how many lines of data to display
$display = 5;
// where to start depending on what page we're viewing
$start = ($page * $display) - $display;
// the actual news we're going to print
$news = array_slice($myArray, $start, $display);
// printing the data
foreach($news as $key=>$value)
{
print("line $key: $value<br>\n");
}
?> |
