从PHP中的多维数组中的最后一个数组返回一个元素

Question

如何在PHP中动态显示最后一个数组中的元素.例如:

Array ( [0] => Array ( [id] => 6 [user_id] => 8 [category_path] => Sport)
        [1] => Array ( [id] => 8 [user_id] => 8 [category_path] => Computers))

为了从最后一个数组返回"id"

8

并为下一个例子

Array ( [0] => Array ( [id] => 6 [user_id] => 8 [category_path] => Sport)
        [1] => Array ( [id] => 8 [user_id] => 5 [category_path] => Computers)
        [2] => Array ( [id] => 16 [user_id] => 45 [category_path] => Soft))

为了回归

   16

谢谢!

试试这个:

function getLastId(&$array){
    $tmp=end($array);
    return $tmp['id'];
}
