How one can set a session variable when a hyperlink is clicked?

I’ve created a search block. It outputs a number of outcomes (names) as hyperlinks. Person can observe Drupal Development hyperlink. How can I cross Drupal Development person identify into $_SESSION variable?

I attempted doing this, Drupal Development consequence exhibits a web page not discovered error.

'identify' => l(t($n['name']), 'edit_details' ,array('question' => array('uid' => $n['uid'])))

In hook_menu() I set $objects['edit_details/%'] to array(). I handed Drupal Development worth into Drupal Development session with $_SESSION['id'] = $_GET['uid'];.
