怎么把下面的JSON写成php数组的形式

这是我用decode dump出来的结果，
["articles"]=> array(2) { [0]=> array(4) { ["title"]=> string(9) "Happy Day" ["description"]=> string(21) "Is Really A Happy Day" ["url"]=> string(3) "URL" ["picurl"]=> string(7) "PIC_URL" } [1]=> array(4) { ["title"]=> string(9) "Happy Day" ["description"]=> string(21) "Is Really A Happy Day" ["url"]=> string(3) "URL" ["picurl"]=> string(7) "PIC_URL" } } } 怎么写？
