title: Url redirection in PHP
body: <p>i am having a url like
  <a href="http://localhost/joomla/Joomla_1.5.7/index.php?option=com_content&amp;view=section&amp;layout=blog&amp;id=3&amp;Itemid=55" rel="nofollow noreferrer">http://localhost/joomla/Joomla_1.5.7/index.php?option=com_content&amp;view=section&amp;layout=blog&amp;id=3&amp;Itemid=55</a></p>
  
  <p>and i want to redirect this to 
  <a href="http://localhost/joomla/Joomla1.5/index.php?option=com_content&amp;view=section&amp;layout=blog&amp;id=3&amp;Itemid=55" rel="nofollow noreferrer">http://localhost/joomla/Joomla1.5/index.php?option=com_content&amp;view=section&amp;layout=blog&amp;id=3&amp;Itemid=55</a></p>
  
  <p>Not only this redirection but whenever i have anything next to Joomla_1.5.7/ i am trying to attach that to Joomla1.5 ..
