Question

我有一个脚本将冲浪者重定向到我网站的各个部分。例如，当我将冲浪者发送到script.php?car=bmw时，它会将冲浪者重定向到http://www.mywebsite.com/bmw

这是脚本的样子：

<?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]);

?>

现在我想将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，当我将冲浪者发送到script.php?car=bmw时，脚本会将用户重定向到bmw部分的随机页面之一。

我可以使用一个数组吗？

Answer 1

您可以使用array_rand -

将它们存储为 -

"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 2

您可以重构数组以包含这种情况下的子类型。像

这样的东西

<?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]))];

?>

Answer 3

＆＃13;

<?php
$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/s","http://www.mywebsite.com/mercedes/d")
);

$car = $_GET['url'];

$rand = rand(0,count($array[$car])-1)

header("Location: " . $array[$car][$rand]);

＆＃13;

Answer 4

您需要使用多维数组和array_rand（）函数。请尝试考虑以下代码：

$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)]);

现在它有一个可以随机化的值数组（array_rand（）可以为你完成这项工作），而不是拥有一个bmw＆＃39;的值。

从数组重定向到随机链接
