PHP when writing to file, How to prepend and append text to a file with existing text?
<p>I'm creating a xml file with PHP here is some sample code.</p>

<pre><code> $myFile = "example_file.xml";
    $fh = fopen($myFile, 'w');
  while($row = mysql_fetch_array($result))
  {

  $stringData = "&lt;field name=\"id\"&gt;$page_id&lt;/field&gt;
                              &lt;field name=\"url\"&gt;http://myfundi.co.za/a/$page_url&lt;/field&gt;
                              &lt;field name=\"title\"&gt;$pagetitle&lt;/field&gt;
                              &lt;field name=\"content\"&gt;$bodytext&lt;/field&gt;
                              &lt;field name=\"site\"&gt;Myfundi&lt;/field&gt;";
                          fwrite($fh, $stringData);
    }             

    fclose($fh);
</code></pre>

<p>What I need to do is when the first content is written to the text file, I need to prepend and append some more text. </p>

<p>I need to prepend  and append  to the data that already exists.</p>

<p>How can I do that?</p>

<p>Thanks</p>
