Question

这是我目前的代码：

<?php
$jsonData = file_get_contents('http://example.com/bin/serp.php?engine=google&phrase=stackoverflow');

$phpArray = json_decode($jsonData);
print_r($phpArray);
?>

现在它在我的页面上显示：

Array ( [0] => stdClass Object ( [idx] => 0 [title] => Stack Overflow [description] => A language-independent collaboratively edited question and answer site for programmers. [url] => http://stackoverflow.com/ ) [1] => stdClass Object ( [idx] => 1 [title] => Stack Overflow - Wikipedia, the free encyclopedia [description] => Stack Overflow website logo.png · Stack Overflow.png.

这就是我试图在PHP页面上显示的内容（这只是前几行，但我想实际使用所有json数据）：

1.  <a href="http://stackoverflow.com/">Stack Overflow</a>
A language-independent collaboratively edited question and answer site for programmers.

2.  <a href="http://en.wikipedia.org/wiki/Stack_Overflow">Stack Overflow - Wikipedia, the free encyclopedia</a>
Stack Overflow website logo.png &middot; Stack Overflow.png. Screenshot of Stack Overflow as of December 2011. Web address &middot; stackoverflow.com. Commercial? Yes.

这部分我似乎并不了解如何获取JSON数据并将其格式化为我想要的。所有数据都在那里，所以如果有人能告诉我我需要在当前代码中更改以使其正常工作，那将非常感激。

解码json字符串时，您将获得一个数组。如果你指定TRUE作为第二个参数，则数组将是关联的。

现在，您只需将数组的内容放在您喜欢的位置，例如：

// here we've the decoded json data
$a = array(
            "link1",
            "desc1",
            "link2",
            "desc2"
     );

// for each data, we make an ordered list with data you need
// in your case you'll have the link and the description on every point
echo "  <ol>
            <li>{$a[0]}</li>
            <li>{$a[1]}</li>
        </ol>

        <ol>
            <li>{$a[2]}</li>
            <li>{$a[3]}</li>
        </ol>   ";

告诉我，如果我不清楚，我会编辑我的答案。

如何显示解码的JSON数据？
