Answer 1

You have also one error in the cycle in your code.

Try this:

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

Answer 2

Try before: echo $json_response set header content type to 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。
