我正在研究一个关于 Bing 及其搜索结果的研究项目，由于我对 PHP 还是很陌生，所以我正在寻找一些帮助。昨天我已经在这里得到了一些帮助，结果非常好，我再次尝试:)

我有以下代码：

<?php
$r = '{"d":{"results":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/Composite?Sources=\u0027web\u0027&Market=\u0027en-US\u0027&Query=\u0027php\u0027&Adult=\u0027off\u0027&$skip=0&$top=1","type":"ExpandableSearchResult"},"ID":"1c509d25-5ca4-4db5-bfc5-cafd6917e2c2","WebTotal":"10600000","WebOffset":"0","ImageTotal":"","ImageOffset":"","VideoTotal":"","VideoOffset":"","NewsTotal":"","NewsOffset":"","SpellingSuggestionsTotal":"","AlteredQuery":"","AlterationOverrideQuery":"","Web":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/ExpandableSearchResultSet(guid\u00271c509d25-5ca4-4db5-bfc5-cafd6917e2c2\u0027)/Web?$skip=0&$top=1","type":"WebResult"},"ID":"4cf2a8d6-21b7-433d-81e9-84e74091a44a","Title":"PHP: Hypertext Preprocessor","Description":"What is PHP? PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML.","DisplayUrl":"www.php.net","Url":"http://www.php.net/"},{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/ExpandableSearchResultSet(guid\u00271c509d25-5ca4-4db5-bfc5-cafd6917e2c2\u0027)/Web?$skip=48&$top=1","type":"WebResult"},"ID":"2d8f8107-895e-4052-9edc-b656e74c3f2e","Title":"CakePHP: the rapid development php framework. Pages","Description":"Official website.

Here we list all of the available presentation categories stored within this system.","DisplayUrl":"talks.php.net","Url":"http://talks.php.net/"}],"Image":[],"Video":[],"News":[],"RelatedSearch":[],"SpellingSuggestions":[]}]}}';
$r = json_decode($r);
foreach($r->d->results as $value) {
  foreach($value->Web as $result) {
    echo $result->Title, "\r\n";
    echo $result->Description, "\r\n";
    echo $result->Url, "\r\n";
  }
}
?>

这基本上显示了来自 Bing 的 json 结果的三个站点的标题、描述和 URL（注意：并不总是只有 3 个结果，通常是 10，但可以是任意数字）

现在这是我的主要任务：对于我的研究项目，我需要随机打乱结果，这意味着我希望看到它，例如：

第一次加载页面： CakePHP：快速开发的php框架。Pages PHP 介绍 PHP：超文本预处理器

第二次加载页面： PHP Presents PHP: Hypertext Preprocessor CakePHP: 快速开发的php框架。页面

第三次加载页​​面： PHP：超文本预处理器 CakePHP：快速开发的php框架。PHP 呈现的页面

同样，上面的顺序只是一个例子——我真的很想要它随机的，没有特定的顺序。

我要感谢我以前的助手，我期待着你的回答。

感谢您花时间阅读本文：）

更新：如果有人这么好心，也给我看一个只对除前三个结果之外的结果进行洗牌的例子——那就太好了。

您可以使用临时数组来存储线条和shuffle随机化它的方法。

<?php
$r = '{"d":{"results":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/Composite?Sources=\u0027web\u0027&Market=\u0027en-US\u0027&Query=\u0027php\u0027&Adult=\u0027off\u0027&$skip=0&$top=1","type":"ExpandableSearchResult"},"ID":"1c509d25-5ca4-4db5-bfc5-cafd6917e2c2","WebTotal":"10600000","WebOffset":"0","ImageTotal":"","ImageOffset":"","VideoTotal":"","VideoOffset":"","NewsTotal":"","NewsOffset":"","SpellingSuggestionsTotal":"","AlteredQuery":"","AlterationOverrideQuery":"","Web":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/ExpandableSearchResultSet(guid\u00271c509d25-5ca4-4db5-bfc5-cafd6917e2c2\u0027)/Web?$skip=0&$top=1","type":"WebResult"},"ID":"4cf2a8d6-21b7-433d-81e9-84e74091a44a","Title":"PHP: Hypertext Preprocessor","Description":"What is PHP?

$r = json_decode($r);
$tmpArray = array();
foreach($r->d->results as $value) {
  foreach($value->Web as $result) {
    $string = $result->Title."\r\n";
    $string.= $result->Description."\r\n";
    $string.= $result->Url."\r\n";
    $tmpArray[] = $string;
  }
}
shuffle($tmpArray);
foreach($tmpArray as $string){
    echo $string;
}
?>

这也可能有效：

$r = json_decode($r);
$r->d->results = shuffle($r->d->results);

编辑：要随机播放除前三个键之外的每个键：

<?php

    $string.= $result->Description."\r\n";
    $string.= $result->Url."\r\n";
    $tmpArray[] = $string;
  }
}
$limit = min(3,count($tmpArray)) -1;
for($i=0;$i<$limit;$i++){
    echo array_shift($tmpArray); // echo and remove first item
}
shuffle($tmpArray);
foreach($tmpArray as $string){
    echo $string;
}
?>
