How to fetch image URL with thumb size?

Answer 1

Use the attributes() method of SimpleXmlElement.

Example:

$imageAttributes = $movie->images[0]->attributes();
$size = $imageAttributes['size'];

See the documentation at: http://www.php.net/manual/en/simplexmlelement.attributes.php

Answer 2

See the below an easy way to get only specific images.

$xml = simplexml_load_file($url);
$images = $xml->xpath("//image");
//echo "<pre>";print_r($images);die;
foreach ($images as $image){
    if($image['size'] == "thumb"){      
        echo "URL:".$image['url']."<br/>";
        echo "SIZE:".$image['size']."<br/>";
        echo "<hr/>";
    }
}

Answer 3

EDIT: select only URL attributes with size = "thumb" and type = "poster" :

$urls = $xml->xpath("//image[@size='thumb' and @type='poster']/@url");

if you expect only 1 url, do:

$url = (string)$xml->xpath("//image[@size='thumb' and @type='poster']/@url")[0];
echo $url;
