------解决方案--------------------
PHP code

$array = array('标题1', 'id1', '标题2', 'id2', '标题3', 'id3');
foreach ($array as $key => $value) {
    if (isset($array[$key + 1]))
        $id = $array[$key + 1];
    echo '<a href="?id=' . $id . '">' . $value . '</a> (id=' . $id . ')<br/>';
}

------解决方案--------------------
PHP code

$array=array();
$arrList=array();
for($i=0; $i<count($list); $i++){
  $array['title'] = $list[$i];
  $array['id'] = $list[$i+1];
  $arrList[] = $array;
}
foreach($arrList as $lists){
  echo "<a href='?id=$lists['id']'>$lists['title']</a>";
}

------解决方案--------------------
PHP code
$array = array('id1','标题1','id2','标题2','id3','标题3');
foreach(range(1,count($array)*1/2) as $val){
    echo "<a href='?id=".current($array)."'>".next($array)."</a>\r\n";
    next($array);
