Answer 1

您的代码循环中也有一个错误。

尝试这个：

if (count($query) > 0) {
    foreach ($query as $queryElement) {
        $el = $queryElement;
        $el['description'] = trim(preg_replace('/\s+/', ' ', strip_tags($el['description'])));
        $arr[] = $el;
    }
}

Answer 2

尝试之前：echo $ json_response将标头内容类型设置为application / json

<?PHP
header('Content-Type: application/json');
echo $json_response;

Answer 3

使用htmlentities()代替strip_tags() ，以保留存储在db中的实际内容。
