从数组重定向到随机链路

Question

我有一个脚本，是重定向冲浪者到我的网站部分。例如，当我向script.php?car=bmw发送surfer时，它是将surfer重定向到http://www.mywebsite.com/bmw

脚本如下所示：

<?php
$array = array(
    "bmw" => "http://www.mywebsite.com/bmw",
    "toyota" => "http://www.mywebsite.com/toyota",
    "mercedes" => "http://www.mywebsite.com/mercedes"
);

$car = $_GET['url'];

header("Location: " . $array[$car]);

?>

现在我想把冲浪者重定向到随机车，例如

"bmw" => "http://www.mywebsite.com/bmw/x1","http://www.mywebsite.com/bmw/x3","http://www.mywebsite.com/bmw/x5",

"toyota" => "http://www.mywebsite.com/toyota/yaris", "http://www.mywebsite.com/toyota/avensis", "http://www.mywebsite.com/toyota/corolla",

"mercedes" => "http://www.mywebsite.com/mercedes/e", "http://www.mywebsite.com/mercedes/s",  "http://www.mywebsite.com/mercedes/d"

因此，当我发送冲浪者到script.php?car=bmw，脚本将重定向用户到一个随机页面从宝马部分。

我可以用一个数组来完成这个任务吗？

Answer 1

您需要使用多维数组和array_rand()函数。试着考虑下面的代码：

$array = array(
    "bmw" => array("http://www.mywebsite.com/bmw/x1","http://www.mywebsite.com/bmw/x3","http://www.mywebsite.com/bmw/x5"),
    "toyota" => array("http://www.mywebsite.com/toyota/yaris", "http://www.mywebsite.com/toyota/avensis", "http://www.mywebsite.com/toyota/corolla"),
    "mercedes" => array("http://www.mywebsite.com/mercedes/e", "http://www.mywebsite.com/mercedes/s",  "http://www.mywebsite.com/mercedes/d")
);

$car = $_GET['url'];

header("Location: " . $array[$car][array_rand($array[$car],1)]);

而不是有一个值的‘宝马’，它现在有一系列的价值可以随机(array_rand()为您做的工作)。

Answer 2

你可以用array_rand -

把它们作为-

"bmw" => "http://www.mywebsite.com/bmw/x1,http://www.mywebsite.com/bmw/x3,http://www.mywebsite.com/bmw/x5",

并使用-

header("Location: " . array_rand(explode(',', $array[$car])));

Answer 3

在本例中，您可以重构数组以包括这些子类型。有点像

<?php
$array = array(
    "bmw" =>array(
        'car1' =>  "http://www.mywebsite.com/bmw/car1",
        'car2' =>  "http://www.mywebsite.com/bmw/car2",
        'car3' =>  "http://www.mywebsite.com/bmw/car3",
        'car4' =>  "http://www.mywebsite.com/bmw/car4",
    ),
    "toyota" =>array(
        'car5' =>  "http://www.mywebsite.com/toyota/car5",
        'car6' =>  "http://www.mywebsite.com/toyota/car6",
    ),
    "mercedes" =>array(
        'car7' =>  "http://www.mywebsite.com/mercedes/car7",
        'car8' =>  "http://www.mywebsite.com/mercedes/car8",
    ),
);

$car = $_GET['url'];

header("Location: " . $array[$car][array_rand($array[$car]))];

?>
