Question

我想将一组图片与每个从列表中随机抽取的引号列表配对，并为该对分配一个唯一的URL。很像The Nietzsche Family Circus。

我很确定他正在使用php为两个列表随机抽取并创建带有图片和引号唯一标识符的网址。

有没有人可以帮助我开始复制这个概念？感谢。

您始终可以使用数据库。如果您在数据库中创建一个表，其中一列用于标识该对的唯一URL，一列用于图像URL，另一列用于引用文本，您可以执行以下操作：

$quoteArray = array(); //in reality this would be filled with your quotes
$imageArray = array(); //this would be filled with your image urls
$pairs = array();
while(count($quoteArray) > 0 && count($imageArray) > 0) {
    $quoteIndex = rand(0, count($quoteArray) - 1); //get some random indexes
    $imageIndex = rand(0, count($imageArray) - 1);
    $pairs[] = array('quote' => $quoteArray[$quoteIndex], 'image' => $imageArray[$imageIndex]);
    unset($quoteArray[$quoteIndex]); //keep us from using the same quote twice
    unset($imageArray[$imageIndex]); //same goes for the images
}

//this assumes your table has an autoincremeting id field
$stmt = $connection->prepare("INSERT INTO awesomeTable (quote, image) VALUES( :quote , :image )");
//$connection is a PDO which you would have created earlier...look in the php manual for information on setting this up

foreach($pairs as $pair) {
    $uniqueId = sha1($quote . $image);
    $stmt->execute(array(':quote' => $pair['quote'], ':image' => $pair['image']));
}

然后，获取随机网址：

$result = $connection->query("SELECT * FROM awesomeTable ORDER BY RAND() LIMIT 1");
$record = $result->fetch();
//record will contain either an object (accessed by $row->url, $row->quote, etc) or an
//associative array (accessed by $row['url'], $row['quote'], etc) depending on how you
//set up the PDO

你提供这些服务的页面（images.php）只会传递一个id（由于它是自动增量的，这将是唯一的）并查询数据库以获取行（因此引用和图像）与该ID相关联。

将随机图像与随机引用配对，并为该对分配唯一的URL
