But that only prints the first 100. Also, there is some bit of redundancy
-- no need to use $i AND $index when both are doing the same thing.
To print the lot in 100-per-"page" chunks is a bit more complex. You have
to:
* Break the array into 100 piece chunks
* Remember from page to page what the last chunk was
* pass that information from page to page
Also, I recommend using a "for" and not a "foreach" loop. It doesn't
matter except for code cleanlines, though.
So assuming an array holds more than 100 items...
(warning, this code is untested)
<?
$page_size = 100;
$page_start=$_GET['page_start']?$_GET['page_start']:0;
$myarray_length = count($myarray);
$subarray = array_slice($myarray, $page_start, $page_size);
$subarray_size = count($subarray);
for ($i = 0; $i < $subarray_size; $i++){
print($i + $page_start . ". ");
print($subarray[$i]) . "<br>\n";
}
print "<a href='?page_start=" . ($page_start - 100) . "'>Last Page</a>";
print "<a href='?page_start=" . ($page_start + 100) . "'>Next Page</a>";
?>
I may have a typo or two in there, and I may have outright screwed
something up, but hopefully you get the idea. later...
