谷歌的建议随机php

Question

我想从google suggest得到随机的建议；但我看到

《赛琳娜》、《赛琳娜·戈麦斯》、《赛琳娜·戈麦斯时代》、《赛琳娜·戈麦斯歌曲》、《赛琳娜·戈麦斯电影》、《赛琳娜·戈麦斯彪马》、《赛琳娜·戈麦斯2018》、《赛琳娜·戈麦斯新歌》、《赛琳娜·戈麦斯网友》、《赛琳娜·戈麦斯专辑》

不要随意工作：

$suggURL =
    'http://suggestqueries.google.com/complete/search?output=firefox&client=firefox&hl=en-US&q=' .
    urlencode("selena");
$context = stream_context_create(array(
    "http" => array(
        "header" =>
            "User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36",
    ),
));
$data = file_get_contents($suggURL, false, $context);
//$data=$this->get_web_page( $suggURL );
$data = preg_replace('/]/', '', $data); // remove numbers
$data = str_replace('[', "", $data);
$data = str_replace('r', "", $data);
$data = str_replace('"', "'", $data);

$data;
$a = ['' . $data . ''];
echo "<br/>";
echo $website = $a[mt_rand(0, count($a) - 1)];
"\n";

Answer 1

$data变量包含一个JSON字符串，所以您对它的处理方式是错误的。请改用json_decode()。

<?php

$suggURL =
    'http://suggestqueries.google.com/complete/search?output=firefox&client=firefox&hl=en-US&q=' .
    urlencode("selena");
$context = stream_context_create(array(
    "http" => array(
        "header" =>
            "User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36",
    ),
));
$data = file_get_contents($suggURL, false, $context);

$a = json_decode($data);

echo "<br/>";
echo $a[1][mt_rand(0, count($a[1]) - 1)];
"\n";

?>

解释：

$data的格式如下：

["selena",["selena gomez","selena","selena gomez age","selena gomez songs","selena movie","selena gomez movies","selena gomez net worth","selena death","selena songs","selena gomez back to you"]]

它是JSON格式，所以对于print_r($a);，使用json_decode()会得到如下结果

Array ( [0] => selena [1] => Array ( [0] => selena gomez [1] => selena [2] => selena gomez age [3] => selena gomez songs [4] => selena movie [5] => selena gomez movies [6] => selena gomez net worth [7] => selena death [8] => selena songs [9] => selena gomez back to you ) )

您现在可以访问$a[1]，它是建议的数组，并从echo $a[1][mt_rand(0, count($a[1]) - 1)];获得随机建议

Answer 2

请仔细检查数组是否被正确处理，您可以使用以下代码从数组中选取随机值

$rant = $data[1][ mt_rand(0, count($data[1])-1 ) ];

下面是一个工作示例；

$data = ["saleena",["saleena","saleena meaning","saleena saleena","saleena clarence","saleena khan","selena gomez songs","saleena shaheen aricent","saleena name meaning","selena songs","selena gomez status"]];
$rant = $data[1][ mt_rand(0, count($data[1])-1 ) ];
