在unity中，我将用户名和密码传递到login.php，然后出现了“mysqlserver away”。我设置如下。
php.ini文件

post_max_size = 750M
upload_max_filezie = 750M
max_execution_time = 1200
max_input_time = 5000
memory_limit = 1000 M
max_allowed_packet = 200M

phpmyadmin/config.inc.php
+添加

$cfg ['ExecTimeLimit'] = 6000;

+添加my.ini

innodb_look_wait_timeout=600

如果我在网址中输入localhost:8080/escape\u room/login.php，结果屏幕会显示很长时间。我想就这件事征求意见。
+登录.php

<?php
$servername = "localhost:8080";
$username="root";
$password="";
$dbName="escape_room";
$user_username = $_POST['Input_user'];
$user_password = $_POST['Input_pass'];
$conn = new mysqli($servername, $username, $password, $dbName);
if(!$conn){
    die("Cound not Connect: " . mysqli_connect_error());
}

$sql = "SELECT pass FROM escape_room WHERE user = '".$user_username."' ";
$result = mysqli_query($conn, $sql);

//Get the result and confirm login 
$numrows = mysqli_num_rows($result);
if($numrows == 0)
{
    die("ID does not exist \n");
}
else{
    while($row = mysqli_fetch_assoc($result)){
        if($row['pass'] == $user_password){ 
            echo "login success";
            echo $row['pass'];  
        }else{
            echo "password incorrect";
            echo "password is =". $row['pass'];
        }

    }
}

?>

错误如下。

mysqli :: _construct(): MySQLserver has gone away
mysqli :: _construct(): Error While reading greeting packet PID=7572
