У меня был этот код, который я написал в прошлом году, и он возвращает RSS-каналы для некоторого срока ввода:
<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 to parse the $row[1] variable to get out words, make new string with a + 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() as $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() as $item) { // echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] .

"</a></li><br>"; - Hide quoted text - "<br><br>\n"; } ?> </body> </html> RSS.php

Однако этот код больше не работает или я не тестирую его правильно … Я запускаю его на xampp на mac.
Я хотел сделать что-то вроде этого:
Пользователь вводит термин, и я хочу отображать каналы RSS из Yahoo, Google или NYTimes.
Благодаря!
EDIT: Я получил два файла RSS.php и Parser.php с сайта в прошлом году, и теперь похоже, что сайт не работает. Я пытаюсь понять, может ли кто-нибудь предложить другое решение. Благодаря!
