Only display elements 5 days old or younger? - php

Question

I am using SimplePie to display the RSS results from multiple sources, however I'm finding that there's several I don't need to see. How do I only show the results that are 5 days old or younger?
Here's my current PHP code:
foreach ($feed->get_items(0) as $item):
$url = $item->get_permalink();
$title = $item->get_title();
$date = $item->get_date('F j, Y - g:i a');
$description = $item->get_description();
if (strpos($url,'craigslist') !== false) {
echo ' <div id="linkCell" style="width: 100%;">';
echo ' <div id="vAlign">';
echo ' <p class="linkTitle">';
echo ' '.$title.'';
echo ' </p><br />';
echo ' <span class="date">'.$date.'</span><br>';
echo ' <p class="description">'.$description.'</p>';
echo ' </div>';
echo ' </div>';
}
endforeach;
Thanks in advance!

Something like this should work. Need to convert date to unix timestamps, find the difference, and then convert this to days.
foreach ($feed->get_items(0) as $item):
$url = $item->get_permalink();
$title = $item->get_title();
$date = $item->get_date('F j, Y - g:i a');
$datestrtotime = strtotime($date);
$now = time();
$datediff = $now - datestrtotime;
$daysdifference = floor($datediff/(60*60*24));
$description = $item->get_description();
if($daysdifference>5)
{
if (strpos($url,'craigslist') !== false) {
echo ' <div id="linkCell" style="width: 100%;">';
echo ' <div id="vAlign">';
echo ' <p class="linkTitle">';
echo ' '.$title.'';
echo ' </p><br />';
echo ' <span class="date">'.$date.'</span><br>';
echo ' <p class="description">'.$description.'</p>';
echo ' </div>';
echo ' </div>';
}
}
endforeach;
