我的菲律宾比索

$arr = array();
$arr["item"]["content"] = htmlentities($content); // $content is dynamic, not fixed template. 
echo json_encode($arr);

有什么可以解决这个问题的吗？

http://php.net/manual/en/json.constants.php

json_encode($arr,true)
json_decode($arr,true)试试这个

尝试使用addcslashes转义双引号

 $content = htmlentities($content);
 $arr["item"]["content"] = addcslashes($content,'"');
 echo json_encode($arr);

我认为你需要这样做：

addslashes(htmlentities($content));

或：

addcslashes(htmlentities($content), '"''/');
