Remove array index based on date - php

Question

I am working with Symfony framework and I have a Controller whose job is to fetch the RSS feeds.
Once I have the fetched feeds in a set of array, I would like to remove those feeds whose date is greater than the date I provide.
So this is the array of object that I get when I fetch the feeds
Array

As you will notice date in above array.
I am passing the above array and date (not the date from an array above but the $date that i would like to match the array date with to exclude the feed or not) in a parameter to a function below
public function isValid($feed, $date)
{
foreach ($feed as $item) {
if ($item->getfeedItemPubDate()->date < $date) {
echo $item->getfeedItemPubDate()->date;
echo "<br>";
}
}
}
I am able to get the list of feeds whose date from array are smaller than $date but what I am stuck at is how to remove those feeds from the array ? and then pass back the new set of array back to the controller.

Answer 1

You can remove array item by unset function. To know key of that item change a little foreach loop. As so, for example
public function isValid($feed, $date)
{
foreach ($feed as $key => $item)
if ($item->getfeedItemPubDate()->date < $date)
unset ($feed[$key]);
}

Answer 2

You can also try the array_filter function to which you provide a callback function, in your case something like
$feed = array_filter($feed, function($item) use($date) {
return ($item->getfeedItemPubDate()->date < $date);
});
where $date is a variable you set before

Answer 3

Try:
public function isValid($feed, $date)
{
foreach ($feed as $item) {
if (strtotime($item->getfeedItemPubDate()->date) < strtotime($date)) {
echo $item->getfeedItemPubDate()->date;
echo "<br>";
}
}
}
