<?php 

$x = 'A fox was <a href="/xyz/dancingwith">Dancing with</a> light. The night <a href="/xyz/treeare">tree are</a> growing.'; 

$doc = new DOMDocument; 
$doc->loadHTML($x); 
$anchors = $doc->getElementsByTagName('a'); 
$len = $anchors->length; 
for($i = 0; $i < $len; $i++) { 
    $newPath = preg_replace('/\s+/', '-',strtolower($anchors->item($i)->nodeValue)); 
    $oldHref = $anchors->item($i)->getAttribute('href'); 
    $url = explode('/', $oldHref); 
    array_pop($url); 
    array_push($url, $newPath); 
    $newUrl = implode('/', $url); 


     $anchors->item($i)->setAttribute('href', $newUrl); 

} 
$newHTML = $doc->saveHTML(); 
echo $newHTML;
