HTML 的

<form action="form.php" method="post">
<p>
  <input type="text" name="titles[]" /><br />
  <textarea name="languages[]" ></textarea><br />
</p>

<p>
  <input type="text" name="titles[]" /><br />
  <textarea name="languages[]" ></textarea><br />
</p>

<input type="submit" name="submit" id="submit" value="Submit">

</form>

PHP

<?php

if (isset($_POST['submit']))
{

   foreach($_POST['languages'] as $key => $language) {
       echo $language = htmlentities($language);
       echo " -- ";
       echo $title    = $_POST['titles'][$key];
   echo "<br/>";

   }
}
?>
