<?
$filename = 'test.php';
if(isset($_REQUEST['Submit'])){
  $somecontent = stripslashes($_POST['somecontent']);
  // Let's make sure the file exists and is writable first.
  if (is_writable($filename)) {
 // In our example we're opening $filename in append mode.
  // The file pointer is at the bottom of the file hence
  // that's where $somecontent will go when we fwrite() it.
  if (!$handle = fopen($filename, 'w')) {
  echo "Cannot open file ($filename)";
  exit;
  }
 // Write $somecontent to our opened fi<form action="" method="get"></form>le.
  if (fwrite($handle, $somecontent) === FALSE) {

  exit;
  }
 echo "Success, wrote ($somecontent) to file ($filename) <a href=".$_SERVER['PHP_SELF']."> - Continue - ";
 fclose($handle);
} else {
  echo "The file $filename is not writable";
  }
  }
