我有一个数组：

$arr_nav = array( array( "id" => "apple", 
          "url" => "apple.html",
          "name" => "My Apple" 
        ),
        array( "id" => "orange", 
          "url" => "orange/oranges.html",
          "name" => "View All Oranges",
        ),
        array( "id" => "pear", 
          "url" => "pear.html",
          "name" => "A Pear"
        )       
 );

我想使用一个foreach循环来替换（仅允许我设置数字：

for ($row = 0; $row < 5; $row++)

能够显示相关数组值的.first和.last类

编辑

我希望将数据回显为：

<li id="' . $arr_nav[$row]["id"] . '"><a href="' . $v_url_root . $arr_nav[$row]["url"] . '" title="' . $arr_nav[$row]["name"] . '">"' . $arr_nav[$row]["name"] . '</a></li>' . "\r\n";

非常感谢您的快速回复。StackOverflow令人震惊！
