programmatically change link URL in view
I don't recommend to use views php module,

Menu item with callback:

The idea here is to override all the links of the titles in your view with one link which pass an argument to custom menu callback, then in the callback, you write your PHP code which does the routing.

to implement this solution you need to do the following:

1- Override the link in the view



2- Create callback using hook_menu():


/**
 * Implements hook_menu().
 */
function mymodule_menu() {

  $items['my-routing/%node'] = array(
    'title' => 'Custom callback',
    'page callback' => 'my_custom_callback',
    'page arguments' => array(1),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

  return $items;
}


3- Create your custom callback to do the routing:



function my_custom_callback($node) {
  switch ($node->type) {
    case 'product' :
      drupal_goto('project/' . $node->nid);
      break;
    case 'post' :
      drupal_goto('blog/' . $node->nid);
      break;
  }
}
