I would like to split a string efficiently into different sub strings like this :

  <li><a href="">One</a></li><li><a href>Two</a></li><li><a href>Three</a></li>.....<li><a herf>Last</a></li>

I would like to split this string in 3 parts and put each string in a variable.

The first variable $first should contain the first li (<li>One</li>) The second variable $second should contain the rest expect the last (<li>Two</li><li>Three</li>.....) The third variable $third should contain the last li (<li>Last</li>)

Anyone can help ?

Should work:

<?php 

$dom = new DOMDocument;
$dom->loadHTML('<li><a href="#">One</a></li><li><a href="#">Two</a></li><li><a href="#">Three</a></li><li><a href="#">Last</a></li>');
$liTags = $dom->getElementsByTagName('li');

$chunks = array();
foreach ($liTags as $li) {
    $chunks[] = '<li>'.strip_tags($li->nodeValue).'</li>';
}

list($first,$second,$third) = array(
   array_slice($chunks,0,1),
   array_slice($chunks,1,count($chunks)-2),
   array_slice($chunks,-1),    
);
