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. :
