Body: <p>This may just be a 5PM Friday issue, but I'm scratching my head over here. I'm trying to associate a string of related entry id's represented by a variable with a new entry via the API. When I pass the variable, only the first one gets inserted into the DB. If I use the string they all get inserted. Here's the insert code:</p>
  
  <pre><code> $article_countries = "1021,1047,1076,1123"; 
  
   $entry-&gt;getContent()-&gt;setAttributes(array(
     'article_countries' =&gt; array(
       $articleCountries
      )
   ));
  </code></pre>
  
  <p>Why is the string working where the variable isn't?</p>

  This may just be a 5PM Friday issue, but I'm scratching my head over here. I'm trying to associate a string of related entry id's represented by a variable with a new entry via the API. When I pass the variable, only the first one gets inserted into the DB. If I use the string they all get inserted. Here's the insert code:

   $entry->getContent()->setAttributes(array(
     'article_countries' => array(
       $articleCountries
      )
   ));
  
  ```
  
  Why is the string working where the variable isn't?

  I dont think you can build arrays in PHP that way and you end up passing `array(0 => '1021,1047,1076,1123')` to the param.
  
  Not shure if passing the string is supported:
  
  ```
  'article_countries' => $article_countries
  
  ```
  
  If not you could build the array like so:
  
  ```
  'article_countries' => array_map('trim', explode(',', $article_countries))
  
  ```
