im试图随机化数据库中的一组结果
这是阵列的基础：
array (size=30)
0 => string '1' (length=1)
1 => string 'jordan' (length=6)
2 => string 'chris' (length=5)
3 => string '1' (length=1)
4 => string '1' (length=1)
5 => string 'card1, card2, card3, card4, card5, card6, card7, card8' (length=54)
6 => string 'card16, card20, card30, card40, card50, card60, card70, card80' (length=62)
7 => string '' (length=0)
8 => string '' (length=0)
9 => string '' (length=0)
10 => string '' (length=0)
11 => string '' (length=0)
12 => string '' (length=0)
13 => string '' (length=0)
14 => string '' (length=0)
15 => string '' (length=0)
16 => string '' (length=0)
17 => string '' (length=0)
18 => string '' (length=0)
19 => string '' (length=0)
20 => string '' (length=0)
21 => string '' (length=0)
22 => string '' (length=0)
23 => string '' (length=0)
24 => string '' (length=0)
25 => string '' (length=0)
26 => string '' (length=0)
27 => string '2013-11-21 04:23:19' (length=19)
28 => string '0' (length=1)
29 => string '0' (length=1)
我想从数组[5]中提取数据并对其进行混洗/随机化
while ($row = mysql_fetch_array($cards, MYSQL_NUM)) {
var_dump($row);
var_dump(array_rand($row[6], 2 ));
}
我尝试过各种各样的事情，现在我正处于困惑的阶段，比刚开始的时候更困惑，有人能帮我吗？
首先分解字符串：
$cards = explode(",", $row[6]);
然后，使用shuffle随机化，并内爆：
shuffle($cards);
$result = implode(",", $cards);
它现在应该是一个混乱的列表。
您可以使用php函数shuffle在数组中随机化。然后你只需要把你想要的数据拉到一个数组中，打乱它，然后显示它：）
试试这个
function getR($ipt)
{
$pieces = explode(",", $ipt);
return $pieces[mt_rand(0,count($pieces)-1)];
}
while ($row = mysql_fetch_array($cards, MYSQL_NUM))
{
echo getR($row[5]);
}
