$emailFields =  array(
    array(
        'name' => 'comments', 
        'type' => 'html', 
        'content' => "ahfsd\jfh/sf's askghaskg sadf"
    ),
);
echo json_encode($emailFields);

打印的是

[{
    "name": "comments",
    "type": "html",
    "content": "ahfsd\\jfh/sf's askghaskg sadf"
}]

为什么json_encode无法转义'？
