title: Array values to string without foreach
body: <p>I am working on system with Zend Framework 1.12.
  I have this array:</p>
  
  <pre><code>array (size=2)
  0 =&gt; string 'Premia pieniężna 3 000,00 zł' (length=33)
  1 =&gt; string 'test' (length=4)
  </code></pre>
  
  <p>Do you have any idea how to get array values as concatenated string?
  I don't want to use foreach, because this array is generated using two foreach already.</p>
  
  <p>(Desired result:</p>
  
  <pre><code>Premia pieniężna 3 000,00 zł
  test
  </code></pre>
