Question

我发送带有AJAX JSON的预先格式化的HTMl， JSON有以下代码，

我正在尝试从数据库中提取数据并回显数组数据，我无法在json_encode中放置foreach循环，因为看起来我的代码在foreach循环中是错误的，

我如何实现这一目标？

echo json_encode(array('returnnews' => '<div class="news-item-page">
                                    <h3 class="text-info" style="margin-top:0">'.$latestnews->news_subject.'</h3>
                                    '.$latestnews->news_content.'


                                </div>
                                <div class="row">
                                    <div class="col-md-6">
                                        <ul class="list-inline blog-tags">
                                            <li>
                                                <i class="fa fa-tags"></i>'.
                                                foreach($news_tag_array as $tag){
                                                <a href="javascript:;">
                                                echo $tag </a>
                                               }

                                            </li>
                                        </ul>
                                    </div>
                               </div>'));

$tags = '';
foreach($news_tag_array as $tag){
   $tags .= '<a href="javascript:;">'.$tag.' </a>';
}
echo json_encode(array('returnnews' =>  '<div class="news-item-page">
                                    <h3 class="text-info" style="margin-top:0">'.$latestnews->news_subject.'</h3>
                                    '.$latestnews->news_content.'
                                </div>
                                <div class="row">
                                    <div class="col-md-6">
                                        <ul class="list-inline blog-tags">
                                            <li>
                                                <i class="fa fa-tags"></i>'.$tags.'</li>
                                        </ul>
                                    </div>
                               </div>'));

首先准备字符串。随你所有的循环。然后将其放入数组并将其发送到json_encode()。得到结果。

$str = '';
foreach($news_tag_array as $tag){
    $str .= '<a href="javascript:;">';
}
echo json_encode(array(
    'returnnews' => '<div ...'.$latestnews.'</div ... '.$str.' ... ',
));

json编码数组
