PHP自动回复消息需要在添加对MySQL数据库的回复之前暂停

我正在使用一个非常简单的方法，使用基本的PHP来开始使用我已经在工作的消息传递功能的自动回复系统。我知道我没有在这里使用最好的安全方法，但这不是什么意思，所以请避免评论脚本的安全性。

现在，当用户从名为reply的表单发送回复时，它会决定用户是否正在使用user_id 0与自动回复功能进行通信。它是，$sarssystem返回1。如果它没有以1的形式返回，则表单将作为一般消息处理，这完全有效。这是表单流程：

///////////// ADD REPLY TO CONVERSATION //////////////////////////////
if(isset($_POST['reply'])){
    $user_id = $_SESSION['userid'];
    $message = $_POST['message'];
    $conversation_id = $_POST['conversation_id'];
    $sarssystem = $_POST['sarssystem'];

    if(isset($sarssystem)){
    if($sarssystem == 1){
        include 'system/sars_system.php';
    } else {

        $reply = str_replace("'","\\'",$message); 


mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$reply','$user_id', NOW(), '', '$conversation_id')");   

    mysqli_query($conn, "UPDATE ap_conversations SET time = NOW() WHERE conversation_id = '$conversation_id'");

    }
    } else {

        $reply = str_replace("'","\\'",$message); 


mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$reply','$user_id', NOW(), '', '$conversation_id')");   

    mysqli_query($conn, "UPDATE ap_conversations SET time = NOW() WHERE conversation_id = '$conversation_id'");

    }
}
//////////////////////////////////////////////////////////////////////

如果它返回1并且您要回复自动服务，它将include一个文件来添加您的消息并自动回复数据库：

系统/ sars_system.php：

if($message == 'hello'){
    $sarsreply = 'hey, how are you?';
}

$usr_message = str_replace("'","\\'",$message);

mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$usr_message','$user_id', NOW(), NOW(), '$conversation_id')");

mysqli_query($conn, "UPDATE ap_conversations SET time = NOW() WHERE conversation_id = '$conversation_id'");

sleep(3);

mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$sarsreply','0', NOW(), '', '$conversation_id')");

正如你所看到的那样，它只是一个非常基本的，只有一个测试才能让它工作，一旦这个工作应该是我可以做更多的工作，我得到的问题是试图添加用户回复并显示它通常，然后在添加AUTOMATED回复之前等待几秒钟。我试图使用sleep()函数，但是当我点击发送添加我的回复时，只是延迟了整个页面，整个页面似乎冻结了3秒钟，然后用户和自动回复都飞到了屏幕同时。我试图首先添加用户回复，然后等待几秒钟，然后将自动回复添加到数据库。是否有其他功能而不是sleep()我可以用来获得这些结果？

AS REQUESTED - 检索消息和显示对话的代码：

$conversation_id = $convoid;   
$res4=mysqli_query($conn, "SELECT * FROM ap_conversations WHERE conversation_id = '$conversation_id'");
while($row4=mysqli_fetch_array($res4))
{   
 $co_conversation_id = $row4['conversation_id'];
 $co_user_one = $row4['user_one'];
 $co_user_two = $row4['user_two'];
 if($co_user_one == $user_id){
    $co_recip = $co_user_two; 
 } else if($co_user_two == $user_id){
    $co_recip = $co_user_one; 
 }
 if($co_recip == '0'){
    $sarssystem = 1;
 } else {
     $sarssystem = 0;
 }
$res5=mysqli_query($conn, "SELECT * FROM ap_messages WHERE conversation_id = '$conversation_id'");
while($row5=mysqli_fetch_array($res5))
{   
 $co_message_id = $row5['message_id'];
 $co_message = $row5['message'];
 $co_sender_id = $row5['sender_id'];
 $co_time_read = $row5['time_read'];

$res6=mysqli_query($conn, "SELECT * FROM ap_users WHERE user_id = '$co_recip'");

答案 0 :(得分：0)

正如评论中所建议的那样，我会使用DATE_ADD()增加时间戳：

if($message == 'hello'){
    $sarsreply = 'hey, how are you?';
}

$usr_message = str_replace("'","\\'",$message);

mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$usr_message','$user_id', NOW(), NOW(), '$conversation_id')");

mysqli_query($conn, "UPDATE ap_conversations SET time = NOW() WHERE conversation_id = '$conversation_id'");

mysqli_query($conn,"INSERT INTO ap_messages (message_id, message, sender_id, time_sent, time_read, conversation_id) 
VALUES ('','$sarsreply','0', DATE_ADD( NOW(), INTERVAL 5 SECOND), '', '$conversation_id')");
