Sorting an array of SimpleXML objects

Question

I\'ve read what I\'ve found on Stackoverflow and am still unclear on this.

I have an array of SimpleXML objects something like this:

array(2) {
  [0]         


        

Answer 1

it's a old thread but here is my solution that a use to extract information from a rss feed in order to sort by title

$xml =  simplexml_load_file('rss.xml');
$msg = array();
$msg_count = $xml->channel->item->count();

for ($x=0;$x<$msg_count;$x++){
    $msg[$x]['titl'] = (string)$xml->channel->item[$x]->title;
    $msg[$x]['link'] = (string)$xml->channel->item[$x]->link;
    $msg[$x]['date'] = (string)$xml->channel->item[$x]->pubDate;
    $msg[$x]['time'] = strtotime(substr((string)$xml->channel->item[$x]->pubDate,4));
    $msg[$x]['desc'] = (string)$xml->channel->item[$x]->description;
    $msg[$x]['auth'] = (string)$xml->channel->item[$x]->author;
}

foreach ($msg as $key => $row) {
    $titl[$key] = $row['titl'];
    $link[$key] = $row['link'];
    $pdat[$key] = $row['date'];
    $time[$key] = $row['time'];
    $cate[$key] = $row['cate'];
    $desc[$key] = $row['desc'];
    $auth[$key] = $row['auth'];
}

array_multisort(
//change $titl to any variable created by "foreach"
    $titl, SORT_ASC,SORT_NATURAL | SORT_FLAG_CASE,
    $msg);
