Question

我有这个代码，效果很好

$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // example url to parse
$rss = simplexml_load_file($url); // XML parser
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src

foreach($rss->channel->item as $item) {
if ($i < 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

$i++;
}

但我想只显示此Feed中的第二项。我怎么能这样做？

Answer 1

更改此

if ($i < 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

到

if ($i == 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

Answer 2

尝试：

$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // example url to parse
$rss = simplexml_load_file($url); // XML parser
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src

print '<a href="'.$rss->channel->item[1]->link.'">'.$rss->channel->item[1]->title.'</a><br />';

Answer 3

只需更改if条件就可以获得第二个会话

<?php 

$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // example url to parse
$rss = simplexml_load_file($url); // XML parser
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src

foreach($rss->channel->item as $item) {
if ($i > 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

$i++;
}
