要求仿照该代码进行编写<?php $code=0; $data=[]; $msg=["获取面板数据失败","获取面板成功"]; include("conn.php"); include("functions.php"); // $sql="select * from panels p left join users u on p.user_id=u.user_id order by p.panel_is_top desc,p.updated_time desc"; $sql="select p.panel_id,p.panel_title,p.panel_content,p.panel_likeit_nums,p.panel_is_top,p.panel_is_essence,p.panel_date,u.user_name from panels as p left join users as u on p.user_id=u.user_id order by p.panel_is_top desc,p.updated_time desc"; $rs=mysqli_query($conn,$sql); $i=0; //拼装data部分的对象数据 while($row=mysqli_fetch_array($rs)){ //读取记录行 $data[$i]["id"]=$row["panel_id"]; $data[$i]["user"]=$row["user_name"]; $data[$i]["likeitNums"]=$row["panel_likeit_nums"]; $data[$i]["topPanel"]=$row["panel_is_top"]; $data[$i]["essencePanels"]=$row["panel_is_essence"]; $data[$i]["date"]=$row["panel_date"]; $data[$i]["content"]=$row["panel_content"]; $data[$i]["title"]=$row["panel_title"]; //get comments $panelId=$row["panel_id"]; $sql="select c.panel_id,c.comment_id,c.comment_content,u.user_name from comments c left join users as u on c.user_id=u.user_id where c.panel_id=$panelId order by c.updated_time desc"; $rs1=mysqli_query($conn,$sql); $j=0; $comments=[]; while($row1=mysqli_fetch_array($rs1)){ $comments[$j]["id"]=$row1["comment_id"]; $comments[$j]["user"]=$row1["user_name"]; $comments[$j]["content"]=$row1["comment_content"]; $j++; } $data[$i]["comments"]=$comments; $rs1=null; $row1=null; $i++; } if(count($data)>0) $code=1; header("content-type:application/json"); echo getApiResult($code,$data,$msg); ?>

好的，根据您提供的代码，以下是经过修改后的 PHP 代码，可以将面板数据以 API 的形式返回给前端：

<?php
$code = 0;
$data = [];
$msg = ["获取面板数据失败", "获取面板成功"];

include("conn.php");
include("functions.php");

$sql = "select p.panel_id,p.panel_title,p.panel_content,p.panel_likeit_nums,p.panel_is_top,p.panel_is_essence,p.panel_date,u.user_name from panels as p left join users as u on p.user_id=u.user_id order by p.panel_is_top desc,p.updated_time desc";
$rs = mysqli_query($conn, $sql);

$i = 0;
while($row = mysqli_fetch_array($rs)) {
    $panelId = $row["panel_id"];

    $panel = [
        "id" => $row["panel_id"],
        "user" => $row["user_name"],
        "likeitNums" => $row["panel_likeit_nums"],
        "topPanel" => $row["panel_is_top"],
        "essencePanels" => $row["panel_is_essence"],
        "date" => $row["panel_date"],
        "content" => $row["panel_content"],
        "title" => $row["panel_title"],
        "comments" => []
    ];

    $sql = "select c.panel_id,c.comment_id,c.comment_content,u.user_name from comments c left join users as u on c.user_id=u.user_id where c.panel_id=$panelId order by c.updated_time desc";
    $rs1 = mysqli_query($conn, $sql);

    $j = 0;
    while($row1 = mysqli_fetch_array($rs1)) {
        $comment = [
            "id" => $row1["comment_id"],
            "user" => $row1["user_name"],
            "content" => $row1["comment_content"]
        ];
        array_push($panel["comments"], $comment);
        $j++;
    }

    array_push($data, $panel);
    $i++;
}

if(count($data) > 0) {
    $code = 1;
}

header("content-type:application/json");
echo getApiResult($code, $data, $msg);
?>

这段代码中，我们首先执行了 SQL 查询，获取到了面板和评论的数据，然后遍历面板数据，通过拼装一个面板对象，并在对象中包含该面板的评论数据，最终将面板对象添加到 $data 数组中。最后，根据 $data 数组的长度，判断是否成功获取到了面板数据，返回对应的 $code 和 $msg。在返回数据之前，使用 header() 函数设置响应头，告诉浏览器返回的是 JSON 格式的数据。
