Question

Ok so I have an XML object.

$articles, I am foreach-ing around this, like so:

foreach($articles as $key => $ind_article) {

}

The problem I have is that the values I need to access are like so:

$ind_article->image;
$ind_article->image2;
$ind_article->image1;

But I can’t set the image source of the article because the key is unknown, yet I know it starts with image. What can I do to the array/object to either order it or display all image values?

Answer 1

foreach($articles as $key => $ind_article) {
    $variables = get_object_vars($ind_article);
    foreach ($variables as $inner_key => $variable) {
         if (strpos($inner_key, "image") === 0) {
              echo "Found image: $variable";
              // This should also work: echo $ind_article->$inner_key;
         }
     }
}
