I wrote this function to fetch a news item off another web page but with
a little modification it should work for you. To use it you needed to
identify a set of of strings in the source to use as anchors ($start,
$end) and then it pulls that section and crops off the anchor text so
you are left with just what you wanted.
<?
function get_item($url, $start, $end) {
global $item;
if(!($fp=fopen($url,"r"))) {
echo $url." is not accessable";
exit;
}
while(!feof($fp)) {
$item.=fgets($fp,255);
}
fclose($fp);
$start_position=strpos($item, $start)+strlen($start);
$end_position=strpos($item, $end);
$length=$end_position-$start_position;
$item=substr($item, $start_position, $length);
}
echo $item;
?>
Soemthing like this might work for you:
<?
$results=search results;
$keyword=search string;
$startposition=strpos($results, $keyword)-200;
$endposition=strpos($results, $keyword)+200;
$length=$endposition-$startposition;
$item=substr($item, $startposition, $length;
echo $item
?>
