title: php foreach loop display all data
body: <p>I have dump problem with foreach loop... 
  I want to display all data in foreach, example:</p>
  
  <pre><code>$data[1] = "Hello"; 
  $data[2] = "my"; 
  $data[3] = "World";
  </code></pre>
  
  <p>I use this script and work</p>
  
  <pre><code>for($i=1; $i&lt;3; $i++){
          $mydata = $data[$i];
          echo $mydata; }
  </code></pre>
  
  <p>This is ok, no problem. 
  But when I want to include $mydata in next script (for saving in txt), he shows only the last word, <em>World</em></p>
  
  <p>Why? How to include all data from variable</p>
