title: how to retrieve text from text are with php on same page
body: <p>I have a text-area, in which I need some text.</p>
  
  <p>I simply need to get that text to be echoed out with PHP, while on the <em>same</em> page</p>
  
  <p>This is my code so far:</p>
  
  <pre><code>&lt;body&gt;
      &lt;br&gt;
      &lt;h1&gt;Charles Dickens&lt;/h1&gt;
      &lt;form action="Charles Dickens.php" method="GET"&gt;
          &lt;hr/&gt;
          &lt;textarea rows="20" cols="100" name="textTest"&gt;This a is the text Testing area.&lt;/textarea&gt;
          &lt;hr/&gt;
      &lt;/form&gt;
  
      &lt;br&gt;
      &lt;br&gt;
  
      &lt;?php 
          $textTest = $_GET['textTest'];
          echo $textTest;
      ?&gt;
  
  &lt;/body&gt;
  </code></pre>
  
  <p>for some reason it's give me an "undefined error", though the variable is defined:</p>
  
  <pre><code>textTest is undefined.
  </code></pre>
