php - foreach で json_decode をループするにはどうすればよいですか?`

Question

Array
(
    [0] => stdClass Object
        (
            [href] => http://www.google.com
            [description] => search
            [extended] => 
            [meta] => x
            [hash] => x
            [time] => 2013-04-09T02:00:57Z
            [shared] => yes
            [toread] => no
            [tags] => 
        )

    [1] => stdClass Object
        (
            [href] => http://shop.frankchimero.com/collections/frontpage/products/the-shape-of-design-digital-preorder
            [description] => 
            [extended] => 
            [meta] => x
            [hash] => x
            [time] => 2013-04-06T19:39:51Z
            [shared] => yes
            [toread] => no
            [tags] => 
        )

そのような配列がありますが、それを解析する方法がわかりません。"foreach 0, 1, 2, 3, etc. get href" はどうすればよいですか?
