如何从此多维 PHP 数组中获取单个值

例print_r($myarray)

Array
(
    [0] => Array
    (
        [id] => 6578765
        [name] => John Smith
        [first_name] => John
        [last_name] => Smith
        [link] => http://www.example.com
        [gender] => male
        [email] => email@example.com
        [timezone] => 8
        [updated_time] => 2010-12-07T21:02:21+0000
    )
)

问题，如何获取 in 单个值，例如：$myarray

echo $myarray['email'];  will show email@example.com
