如何将现有MySQL数据库导入Amazon RDS？

我可以使用JavaScript的split来将逗号分隔的项列表放在数组中:

var mystring = "a,b,c,d,e";
var myarray = mystring.split(",");

我想到的是有点复杂.我有这个逗号分隔的字符串:

"mystring_109_all,mystring_110_mine,mystring_125_all"

我如何将此字符串拆分为数组

我使用"paypal"付款方式:

$payer = new Payer();
$payer->setPaymentMethod('paypal');

我尝试了以下内容,但它没有设置地址:

$addr = new Address();
$addr->setLine1('34/1');
$addr->setLine2('xxx');
$addr->setCity('xxxxxxx');
$addr->setCountry_code('US');
$addr->setPostal_code('43210');
$addr->setState('OH');

我想知道android mobile中localstorage的物理位置在哪里.

我想从表中检索最大日期.

任何人都可以知道,将mysql查询转换为php数组:

这是mysql查询:

SELECT SUM(time_spent) AS sumtime, title, url 
FROM library 
WHERE delete_status = 0 
GROUP BY url_id 
ORDER BY sumtime DESC

我想将此查询转换为简单的php数组.

如何使用jquery禁用firefox默认图像大小调整行为.

如何从json对象中删除引号:

使用php,我得到以下格式的数据(使用console.log()显示数据)

[
    ["Catching the Wind in Rural Malawi § SEEDM...", "3"], 
    ["Engineering § SEEDMAGAZINE.COM...", "2"], 
    ["Technology Review India: Nissan's Lea...", "2"], 
    ["Alternative Fuel Consulting & Technical Tr...", "2"], 
    ["MIT OpenCourseWare | Science, Technology, ...", "2"]
]

如何使用jquery/json删除引号,我需要这样的字符串(数字周围没有引号):

[
    ["Catching the Wind in Rural Malawi § SEEDM...", 3], 
    ["Engineering § SEEDMAGAZINE.COM...", 2], 
    ["Technology Review India: Nissan's Lea...", 2], 
    ["Alternative Fuel Consulting & Technical Tr...", 2], 
    ["MIT OpenCourseWare | Science, Technology, ...", 2]
]

我有一个像这样的php数组:

 Array
    (
        [0] => Array
            (
                [url_id] => 2191238
                [time_spent] => 41

            )

        [1] => Array
            (
                [url_id] => 2191606
                [time_spent] => 215

            )
        [2] => Array
            (
                [url_id] => 2191606
                [time_spent] => 25

            )
    )

那么,如何time_spent通过url_id 获取基于组的SUM(使用array_count_values)
