Trim characters from RSS feed - php

Question

I'm calling in a RSS feed to my website using PHP. Currently my code below is calling in the entire contents for pubDate:
<pubDate>Thu, 12 Sep 2013 07:23:59 +0000</pubDate>
How do I just display the day and month from the above example i.e. 12 Sep?
EDIT
I should clarify, the above line of code is an example output I currently get but as I'm calling the latest 3 posts from an RSS feed, this date and time will vary. I therefore need the code to be more dynamic (if that's the right term!)
This code is my full code that fetches the contents of an RSS feed:
<?php
$counter = 0;
$xml=simplexml_load_file("http://tutorial.world.edu/feed/");
foreach ($xml->channel->item as $item) {
$title = (string) $item->title; // Title Post
$link = (string) $item->link; // Url Link
$pubDate = (string) $item->pubDate; // date
$description = (string) $item->description; //Description Post
echo '<div class="display-rss-feed"><a href="'.$link.'" target="_blank" title="" >'.$title.' </a><br/><br/>';
echo $description.'<hr><p style="background-color:#e4f;">'.$pubDate.'</p></div>';
if($counter == 2 ) {
break;
} else {
$counter++;
}
} ?>

Answer 1

Use strtotime and date:
$pubDate = 'Thu, 12 Sep 2013 07:23:59 +0000';
$pubDate = date('j M', strtotime($pubDate)); //This is the only one you need!
var_dump($pubDate); //string(6) "12 Sep"

Answer 2

You can parse the date using date_parse and then use the values of month and day in the resulting array.

Answer 3

you can use preg_match() function with desired regular express to fetch particular data.
for example
$content="Thu, 12 Sep 2013 07:23:59 +0000";
preg_match("/.*,(. *)20[0-9][0-9]/"," $content",$g_val) ;
$g_val[1] would have " 12 Sep"

Answer 4

Even this works
<?php
$str="<pubDate>Thu, 12 Sep 2013 07:23:59 +0000</pubDate>";
$str=explode(" ",$str);
echo $str[1]." ".$str[2];//12 Sep
EDIT:
<?php
$counter = 0;
$xml=simplexml_load_file("http://tutorial.world.edu/feed/");
foreach ($xml->channel->item as $item) {
$title = (string) $item->title; // Title Post
$link = (string) $item->link; // Url Link
$pubDate = (string) $item->pubDate; // date
$pubDate=explode(" ",$pubDate);
$pubDate = $pubDate[1]." ".$pubDate[2];
$description = (string) $item->description; //Description Post
echo '<div class="display-rss-feed"><a href="'.$link.'" target="_blank" title="" >'.$title.' </a><br/><br/>';
echo $description.'<hr><p style="background-color:#e4f;">'.$pubDate.'</p></div>';
if($counter == 2 ) {
break;
} else {
$counter++;
}
} ?>
