Json Array数据在php中插入Null值

Question

Json Array数据在php中插入Null值。您好，我有这个想要插入数据库的Json数组数据。除了消息正文/内容插入空值

外，一切正常

Array ( 
    [0] => Array ( 
        [date] => 1435697125 
        [folders] => Array ( 
            [0] => \Important 
            [1] => INBOX 
            [2] => \Inbox 
            [3] => [Gmail]/Important 
        ) 
        [addresses] => Array ( 
            [from] => Array ( 
                [email] => chine@gmail.com 
                [name] => chinelo Goodman  
            ) 
            [to] => Array ( 
                [0] => Array ( 
                    [email] => mic@gmail.com 
                    [name] => michael noway 
                ) 
             ) 
         ) 
         [sources] => Array ( 
             [0] => Array ( 
                 [label] => mic::gmail
                 [resource_url] => http://myserver.com 
             ) 
         ) 
         [subject] => Re: Testing of Data 
         [references] => Array ( 
             [0] => 
             [1] => 
             [2] => 
         ) 
         [in_reply_to] => 
         [id1] => 55930 
         [id2] => 
         [id3] => 14e46 
         [thread_id] => 14e45 
         [person_info] => Array ( 
             [chine@gmail.com] => Array ( 
                 [thumbnail] => http://localhost/contact.png 
             )
             [mic@gmail.com] => Array ( 
                 [thumbnail] => https://localhost/mic.png 
             ) 
         ) 
         [date_received] => 1435697125 
         [date_indexed] => 1435697307 
         [body] => Array ( 
             [0] => Array ( 
                 [type] => text/plain 
                 [charset] => utf-8 
                 [content] => 
                     Thank You. I hope to hear from you sooneer On

             ) 

这是我的insert语句的样子

foreach ($result as $value) {

}

$statement= $db->prepare('
    INSERT INTO 
        json_table(
            date_received,
            date_indexed,
            message_content
        )
        values (
            :date_received,
            :date_indexed,:message_content)
');

$statement->execute(
    array( 
       ':date_received' => $value['date_received'],
       ':date_indexed' => $value['date_indexed'],
       ':message_content' => $value['addresses']['body'][0]['type']['charset']['content']
    )
);

在date_recieved不断插入date_indexed或空数据时插入message_content和NULL。 我如何将消息内容/正文插入数据库。

任何帮助将不胜感激

Answer 1

你的价值观错了......

$statement->execute(array( 
':date_received' => $value[0]['date_received'],
':date_indexed' => $value[0]['date_indexed'],
':message_content' => $value[0]['body'][0]['content']
));

你的转储似乎缺少3个右括号。

不确定你为什么

'：message_content'=＆gt; $值[ '地址'] [ '体'] [0] [ '型'] [ '字符集'] [ '内容']

类型，字符集和内容是同一级别的不同元素，您只需要这个

'：message_content'=＆gt; $值[ '地址'] [ '体'] [0] [ '内容']
