PHP获取XML值，FOREACH创建用户和复制图像。 怎么了？

Question

So i have this cron.php to do some tasks every 15minutes. Cron works fine, but something is wrong with my php code and i cant figure it out.

I want to copy the remote xml file to local folder (this works), then, parse thru the xml file and get all display_name and image_url values. Then, create local folder with username and copy its thumb there... how hard can this be? i've been at it for past 5 days :(

Can you help?

#!/usr/local/bin/php -f

<?php

// Copy remote xml to local dir

copy ('http://www.remoteweb.com/api/?format=xml', '/includes/cache/feed.xml');


// connects to xml
$xmlor = '/includes/cache/feed.xml';
$doc = New DOMDocument();
$doc->load($xmlor);
// gets xml values as vars
$resource = new SimpleXMLElement($xmlor, null, true);

foreach( $doc->getElementsByTagName('display_name') as $user ) {

// create dir with username
if (!file_exists('/includes/cache/_thumbs/'$user'')) {
    mkdir('/includes/cache/_thumbs/'$user'', 0755, true);
}

foreach( $doc->getElementsByTagName('image_url') as $thumb ) {
// copy user thumb to user folder
copy ($thumb, '/includes/cache/_thumbs/'$user'');
                        }
                }
?>

XML Example:

<response>
<resource>
<display_name>Madsprings</display_name>
<image_url>https://serverexample.com/avatar/madsprings.jpg</image_url>
</resource>
</response>

So i changed the code to this,

$xml = simplexml_load_file("/home/sgs/public_html/includes/cache/ctbfeed.xml");

foreach($user = $xml->xpath("//response//resource//display_name") as $ctb_user){
echo $ctb_user;

if (!file_exists('/includes/cache/_thumbs/' . $ctb_user)) {
    mkdir('/includes/cache/_thumbs/' . $ctb_user, 0755, true);
        }

foreach($thumb = $xml->xpath("//response//resource//image_url") as $thumb_url){
$path = parse_url($thumb_url, PHP_URL_PATH);
$local_thumb = basename($path);
copy ($thumb_url, ('/includes/cache/_thumbs/' . $ctb_user . '/' . $local_thumb));
        }
}

And it appears to be working :)
