How to extract an nid from and EntityFieldQuery

Question

I'm trying to figure out if a node already exist, I'm using the following code

$query = new EntityFieldQuery;        
$result = $query
                      ->entityCondition('entity_type', 'node')
                      ->propertyCondition('type', 'item')
                      ->propertyCondition('title', $full_name)
                      ->execute();

       if (!empty($result['node'])) {
         // do something
       }

The problem is this, when a result is returned, the structure of the result is this

    Array
    (
        [node] => Array
            (
                [96] => stdClass Object
                    (
                        [nid] => 96
                        [vid] => 96
                        [type] => item
                    )

            )

)

I'm trying to get the nid, but I can't figure out how to access it $

result['node'][0]

does not work. How do I get the nid in this situation

Answer 1

Jimajamma is correct: The question you ask is a PHP one. You want array_keys($result['node']), since the EntityFieldQuery always returns entities as an array of types, with each type having an array of entities keyed by their unique ID.

However... This query won't tell you if the node already exists or not. It will only tell you that there's a node with that title. That might be adequate for your project, however.

Answer 2

$nid = current($result['node'])->nid;

Answer 3

This appears to be a php question, as basically it looks like you are wanting the first item in your array regardless of its key. In this case that appears to be your nid, or 96. Regardless, you can accomplish this with either of the array_slice(0,1) or array_values() functions.
