这里有一些不寻常的字符导致json_encode在数组中没有正确地将字符串编码为json。

这是我的代码，其中$ about_us是上面的字符串

$about_us = utf8_encode($about_us);
$about_us = htmlentities($about_us, ENT_QUOTES | ENT_IGNORE, "UTF-8");
$about_us = mysql_real_escape_string($about_us);

$link_array = array();
$link_array['stuff'] = 'other string';
$link_array['about_us'] =  $about_us;
$json= json_encode($link_array);

然后我将$ json存储在mysql文本字段中。然而。我可以从检查$ json字符串看到它是无效的json并在http://jsonlint.com/上失败。当我做一个json_decode的东西工作正常，但关于我们是空的。

这是about_us属性的数据库中的内容：

&lt;div id=&quot;site-summary&quot;&gt;\r\n             &lt;p&gt;&lt;strong&gt;Welcome to Whiteley Helyar.&lt;/strong&gt; We are independent, friendly and professional, always seeking to achieve the best for our clients.

请提出任何想法

编辑：这与链接的问题不同，因为utf8_encode在这里没有帮助（这是该问题的可接受答案）。

首先，如果您仍在使用mysql_real_escape_string，那么您可能没有使用PDO与数据库进行交互。你现在真的应该使用PDO。

如果您使用PDO，它可以解决您的许多问题，您可以做一些简单的事情：

$db = new PDO('mysql:host=CHANGE_THIS_TO_YOUR_HOST_NAME;
    dbname=CHANGE_THIS_TO_YOUR_DATABASE',
    'CHANGE_THIS_TO_YOUR_USERNAME',
    'CHANGE_THIS_TO_YOUR_PASSWORD');


$about_us = '<div id="site-summary">
            <p><strong>Welcome to Whiteley Helyar.</strong> We are independent, friendly and professional, always seeking to achieve the best for our clients.

            </div>';

$link_array = array();
$link_array['stuff'] = 'other string';
$link_array['about_us'] =  $about_us;
$json= json_encode($link_array);

$query = $db->prepare("INSERT INTO settings 
    (json) VALUES (:json)
    ");
$query->bindValue(':json', $json, PDO::PARAM_STR);
$query->execute();

然后，如果你查看数据库并将json字段中的内容复制并粘贴到jsonlint中，它将验证就好了。另外，这样，html实际上在数据库中是可读的（而不是必须存储<和"等所有内容。

如何将此字符串存储为mysql中的有效json（utf8_encode和htmlentities没有帮助）
