假设我有一个模拟数据库表的数组.每个数组元素代表一行,每行内是另一个包含字段名称和值的数组.

Array
(
    [0] => Array
        (
            [name] => 'Sony TV'
            [price] => 600.00
        )

    [1] => Array
        (
            [name] => 'LG TV'
            [price] => 350.00
        )

    [2] => Array
        (
            [name] => 'Samsung TV'
            [price] => 425.00
        )  
}

我想要做的是按价格对行(外部数组元素)进行排序.下面是我想要实现的一个例子:

Array
(
    [0] => Array
        (
            [name] => 'LG TV'
            [price] => 350.00
        )

    [1] => Array
        (
            [name] => 'Samsung TV'
            [price] => 425.00
        )

    [2] => Array
        (
            [name] => 'Sony TV'
            [price] => 600.00
        )        
} …

我有一个像这样的数组:

Array
(
    [0] => Array
        (
            [title] => some title
            [time] => 1279231500
        )

    [1] => Array
        (
            [title] => some title 2
            [time] => 1279231440
        )

    [2] => Array
        (
            [title] => some title 3
            [time] => 1279229880
        )
)

我怎么能根据时间对它进行排序？
