title: var_dump displays text, but echo does not
body: <p>I have an array called <code>$worker</code><br>
  the array consists of only strings, each of which has multiple lines.</p>
  
  <p>if I do </p>
  
  <pre><code>var_dump($worker); 
  </code></pre>
  
  <p>it displays all the information, but do </p>
  
  <pre><code>for($i=0,$size=sizeof($worker);$i&lt;$size;++$i)
  {
      echo $worker[i];
  }
  </code></pre>
  
  <p>I end up with nothing on the page.</p>
  
  <p>I'm very new to php, so sorry if this is a noob question:
  how do I get the information in the array to print to the screen correctly?</p>
