how to sort a feed

[mraza]

Hi, I am reading a feed with this code

 

foreach ($xml->channel->item as $item) { 
echo $item->title;
echo '<br>';
}

and outputs

title 1
title 2
title 3
.... and so on until 10

 

I wants in reverse order to output last rss feed first like:

title 10
title 9
title 8
.... and so on until 1

, how can i do it? i tried with rsort($xml->channel->item) butt getting this error:

Warning: rsort() expects parameter 1 to be array, object given in

Thanks for help

well..only going by the code you posted, one way to do it would be

 

foreach ($xml->channel->item as $item) { 
  echo $titles[] = $item->title;
}
$titles = array_reverse($titles);
foreach ($titles as $title) { 
  echo $title . "<br/>";
}

 

Though I have a sneaking suspicion there might be a built-in way to do it, depending on what you are using to get that xml object

You'd need to first put all of the data into an array, and then sort it using that function.

 

$array = array();

foreach ($xml->channel->item as $item) { 
    $array[] = $item->title;
}

$array = array_reverse($array);

foreach($array as $item) {
    echo $item . "<br />";
}

Edit: Crayon always beats me to it...

@mattal999 : rsort() sorts descending alphabetically...not the same as outputting in reverse order.

$mattal999 : rsort() sorts descending alphabetically...not the same as outputting in reverse order.

 

I was just going with the function that was originally suggested in the main post. I've updated my post to use array_reverse.

fair enough.  I almost did the same thing

Thank you sir, i actually had that array idea but is not there any other way that it can sort $xml items without adding this step to loop through all feed. Is it possible i will no need to assign new array for every elements i need like  -link -title etc and i dont need to change $xml->channel->item as $item  ?

 

Thanks and Regards

 

Edit: i m using this to get feed $xml = simplexml_load_file($feedurl);

If you wanted more than one piece of information, then use a multi-dimensional array. Change:

 

$array[] = $item->title;

To:

 

$array[] = array(
    "title" => $item->title,
    "link" => $item->link 
);

HI, I am having a wierd problem using abvoe method. here is my code

$items = array();
foreach ($xmlload->channel->item as $item) { 
$ns_content = $item->children('http://purl.org/rss/1.0/modules/content/');
$desc = $ns_content->encoded;
$description = $item->description;
// echo $description; // this looks nomal here on echo
$categories = array();
                foreach ($item->children() as $child) {
                    if ($child->getName() == 'category') {
                        $categories[] = (string) $child;
                    }
                }

    $items[] = array(
				"title" => $item->title,
				"link" => $item->link,
				"desc" => $desc,
				"description" => $description,
				"categories" => $categories
			);
}

$items = array_reverse($items);	
print_r($items);

when i do print_r i get this result

[0] => Array
        (
            [title] => SimpleXMLElement Object
                (
                    [0] => Title of post
                )

            [link] => SimpleXMLElement Object
                (
                    [0] => http://www.linktofeed.html
                )
            [desc] => SimpleXMLElement Object
                (
                )

            [description] => SimpleXMLElement Object
                (
                )

            [categories] => Array
                (
                )

        )

 

in [description] i am getting SimpleXMLElement Object as description not original one. I tried to output echo as in above code

// echo $description; // this looks nomal here on echo

 

and there it display correct description but not when added in $items description. any help?

Thanks
