Question

I’ve created a table that is being populated by data from an XML file using SimpleXML function of PHP. What I would like to do is to add paging capability wherein if the rows becomes 5 or more then page 2 will be and so on. How to do that?

Answer 1

Given XML:

<root>
<item page="1" title="title 1" />
<item page="2" title="title 2" />
<item page="3" title="title 3" />
<item page="4" title="title 4" />
<item page="5" title="title 5" />
<item page="6" title="title 6" />
<item page="7" title="title 7" />
<item page="8" title="title 8" />
<item page="9" title="title 9" />
<item page="10" title="title 10" />
<item page="11" title="title 11" />
</root>

PHP:

<?php
$xml = simplexml_load_file('yourxml.xml');

$limit = 5;
$page = $_GET['page'];

foreach ( $xml->item as $item ) {
  if ( empty($page) ) {
    if ( $item->attributes()->page > 0 && $item->attributes()->page <= $page+$limit )
      echo $item->attributes()->title,'<br/>';
    } else {
    if ( $item->attributes()->page > ($page-1)*$limit && $item->attributes()->page <= (($page-1)*$limit)+$limit )    
      echo $item->attributes()->title,'<br/>';
  }
}
?>

Then you can access using yourpage.php?page=2 etc etc.
