title: Missing value in associative array, but value visible with var_dump()
body: <p>I have a simple associative array called <code>$product</code>.</p>
  
  <p>This is how it looks with <code>var_dump[$product]</code></p>
  
  <pre><code>array(5) {
    ["sku"]=&gt;
    string(9) "001R00610"
    ["name"]=&gt;
    string(28) "Xerox 001R00610 Transfer Kit"
    ["image_label"]=&gt;
    string(28) "Xerox 001R00610 Transfer Kit"
    ["small_image_label"]=&gt;
    string(28) "Xerox 001R00610 Transfer Kit"
    ["thumbnail_label"]=&gt;
    string(28) "Xerox 001R00610 Transfer Kit"
  }
  </code></pre>
  
  <p>But when i try and get the value of sku with <code>var_dump($product['sku'])</code> it returns null?</p>
  
  <p><code>var_dump($product['sku']);</code></p>
  
  <p>returns</p>
  
  <p><code>NULL</code></p>
  
  <p>I have noticed there seems to be a linebreak in at <code>sku</code>, but i am not sure what is causing this or if this is related to my issue.</p>
