Answer 3

Hier ist, wie es mit DOMDocument und XPath zu tun:

$html = ' 

<a class="out" href="www.a.com/hgfgtsdfdffsdfsdf">sdfsssdfddf</a> 
<a href="www.a.com/hgfgt">dsfdsf</a> 
<a class="menu" href="www.a.com/hgfgt">menu1</a> 
<a class="menu" href="www.a.com/hgfgdfg">menu2</a> 
<a class="menu" href="www.a.com/hgfgdfg">menu3</a> 
<a href="www.a.com/hgfgtssdfdfsdf">sdfsdfddf</a> 
<a href="www.a.com/hgfgtsdfsfsdfdf">sdfsdfsddf</a> 
<a href="www.a.com/hgfgtsdfsdfsdf">sdfsdfddf</a> 
<a class="out" href="www.a.com/hgfgtsdfsdfsdf">sdfsdfddf</a> 

'; 

$classname = 'menu'; // class to find 

$doc = new DOMDocument(); 
$doc->loadHTML($html); 

$xpath = new DOMXPath($doc); 

$result = $xpath->query("//*[contains(@class, '$classname')]"); 

foreach($result as $elem) 
{ 
    echo "title: " . $elem->nodeValue . "<br />"; 
    echo "link: " . $elem->getAttribute('href') . "<br />"; 
}
