我正在使用Symfony框架，我有一个控制器，其工作是获取RSS源。
我在一组数组中获取了已提取的Feed后，我想删除那些date大于我提供的日期的Feed。
所以这是我获取提要时获得的对象数组

正如您将注意到上面数组中的date。
我正在传递上面的数组和日期（不是date来自上面的数组，而是$date，我希望与数组日期匹配，以便在参数中排除Feed）到下面的函数
public function isValid($feed, $date)
{
foreach ($feed as $item) {
if ($item->getfeedItemPubDate()->date < $date) {
echo $item->getfeedItemPubDate()->date;
echo "<br>";
}
}
}
我可以获取其中date数组小于$date的Feed列表，但我坚持的是如何从阵列中删除这些Feed？然后将新的数组传回给控制器。

您可以通过取消设置功能删除数组项。要知道该项的关键，请更改一个foreach循环。如此，例如
public function isValid($feed, $date)
{
foreach ($feed as $key => $item)
if ($item->getfeedItemPubDate()->date < $date)
unset ($feed[$key]);
}

你也可以试试你提供回调函数的array_filter函数，例如
$feed = array_filter($feed, function($item) use($date) {
return ($item->getfeedItemPubDate()->date < $date);
});
其中$date是您在
答案 2 :(得分：0)
尝试：
public function isValid($feed, $date)
{
foreach ($feed as $item) {
if (strtotime($item->getfeedItemPubDate()->date) < strtotime($date)) {
echo $item->getfeedItemPubDate()->date;
echo "<br>";
}
}
}
