Via a DOMdocument:

PHP Code:


			
function getPage($url="http://www.example.com/"){
    $ch = curl_init();
    $useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1"; 
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_FRESH_CONNECT,TRUE);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,15);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
    curl_setopt($ch,CURLOPT_REFERER,'http://www.google.ch/');
    curl_setopt($ch,CURLOPT_TIMEOUT,30);
    curl_setopt($ch,CURLOPT_USERAGENT, $useragent);
    //curl_setopt($ch,CURLOPT_RANGE,0-4096);
    $html=curl_exec($ch);
    curl_close($ch);
    return $html;
}

function getLinks($url){
    //Fetch a page HTML via curl
    $html=getPage($url);
    
    $dom=new DOMDocument();

    //As I load HTML, I'm not sure it's valid, so I clean it up via tidy first
    $tidy = new tidy;
    $tidy->parseString($html);
    $tidy->cleanRepair();
    $html=$tidy->value;

    $html=tidy_repair_string($html);
    $ret=$dom->loadHTML($html);
    
    //And now we parse our HTML the DOM way
    foreach($dom->getElementsbytagname('a') as $k=>$n){
        $href=$n->getAttribute('href');
        if(strpos($href,'http')===0){
            $aryLnk[$href]=1;
        }
    }
    
    foreach($aryLnk as $href=>$junk){
        echo"I will grab <a href=\"$href\">$href</a>:<br>";
        echo<<<html
            <img src="http://web-screenshots.com/free/$href" title="$href"/><hr>
html;
    }
}
