A nice little start on the subject, and as DeMo said there is always more than one way to skin a cat (as the saying goes).

Using DOM & XPath, we could condense:

PHP Code:


			
$pos = strpos($str, "<div id=\"popsearchbd\"");

$pos = $pos + strlen("<div id=\"popsearchbd\"");

 

if($pos == false) {

    echo "No information available";

}

else {

 

    while(1) {

        $pos = strpos($str, "fp-buzzmod\">", $pos);

 

        if($pos === false) {

            break;

        }

 

        $pos = $pos + strlen("fp-buzzmod\">");

        $temppos = $pos;

        $pos = strpos($str, "</a>", $pos);

 

        $datalength = $pos - $temppos;

 

        $data = substr($str, $temppos , $datalength);

        echo $data;

        echo "\n";

    }

 

}

into:

PHP Code:


			
$links = $xpath->query('//div[@id="popsearchbd"]//a');

Now, depending on your skill level or experience with XPath (and/or string functions!) the latter might be even more scary that Sunhil's version! One thing to note is that (at least for the Yahoo site in this tutorial) a User Agent is required, else Yahoo will send back different HTML (not containing the top searches!). However, in the tutorial Sunhil sends along a UA string in the headers so that's ok. :
