<html> <body> <form name="form" action="search.php" method="get"> <input type="text" name="q" /> <input type="submit" name="submit" value="search" /> </form> <?php require_once "rss.php"; // want parse $row[1] variable out words, make new string + instead of spaces $college = "college"; $collegelen= strlen($college); for($i = 0; $i < $collegelen; $i++){ if ($college{$i} == " ") {$spaced = $spaced . "+";} else {$spaced = $spaced . $college{$i};} } echo("yahoo! news rss"); $rss_yahoo =& new xml_rss("http://news.search.yahoo.com/news/rss?p=" . $spaced . "&ei=utf-8&fl=0&x=wrt"); $rss_yahoo->parse(); foreach ($rss_yahoo->getitems() $item) { echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] . "</a></li><br>"; //echo $item['pubdate'] ."<br>"; echo $item['description'] . "<br><br>\n"; } //echo("google rss"); //$rss_google =& new xml_rss("http://news.google.com/news?hl=en&ned=us&q=" . $spaced . "&ie=utf-8&nolr=1&output=rss"); //$rss_google->parse(); //foreach ($rss_google->getitems() $item) { // echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] . "</a></li><br>"; // echo $item['description'] . "<br><br>\n"; } echo("google rss"); $rss_google =& new xml_rss("http://news.google.com/news?hl=en&ned=us&q=" . $spaced . "&ie=utf-8&nolr=1&output=rss"); $rss_google->parse(); foreach ($rss_google->getitems() $item) { echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] . "</a></li><br>"; - hide quoted text - "<br><br>\n"; } ?> </body> </html> rss.php
