title: PHP: email subject
body: <p>I have a form on an intranet and when someone fils out the form it sends an internal email to a certain department.<br>
  I'm trying to get one of arrays to populate into the subject line but just can't figure out how. </p>
  
  <p>The way I populate the array into the body which works fine is as follows:</p>
  
  <pre><code>&lt;?php
      # .. snip ..
      $message = $message.'&lt;tr&gt;
      &lt;td colspan="4" valign="top" class="style7"&gt;&amp;nbsp;&lt;/td&gt;
      &lt;/tr&gt;';                                                                                                                     
      for($i = 0; $i &lt; count($arrEncoding); $i++) {
          $desc= $arrEncodingDesc[$i];    
          $value= $arrEncoding[$i];                                                         
          if ($_POST[$arrEncoding[$i]]) {                                  
              $message = $message.'&lt;tr&gt;&lt;td colspan="4" valign="top" class="style4"&gt;'.$desc.'&lt;/td&gt;&lt;/tr&gt;';                               
          }
      }
      # .. snip ..
  ?&gt;
  </code></pre>
  
  <p>I tried a number of ways and below is just an example of one of the ways I've tried it:</p>
  
  <pre><code>$subject = $message.'Event Request Form:'.$arrEncoding[$i];
  </code></pre>
  
  <p>So basically I need the array of arrEncoding to populate into the subject field.<br>
  Any help would be greatly appreciated. I don't know if my question is concise enough, I'm still very much a beginner to the whole php world.</p>
