Question

我尝试将数据存储到数据库中。但我得到“MySQL服务器消失”的错误。任何人都可以帮我找出我的错误吗？

实际上这是Basic PHP爬虫之一。我是这个人的初学者。所以帮帮我!!!

Connection.php：

<?php
$hostname_TestConnection = "******";
$database_TestConnection = "*******";
$username_TestConnection = "*******";
$password_TestConnection = "********";
$TestConnection = mysqli_connect($hostname_TestConnection, $username_TestConnection, $password_TestConnection) or trigger_error(mysqli_error($TestConnection),E_USER_ERROR); 
?>

的index.php：

<?php require_once('Connections/TestConnection.php');
include_once('simple_html_dom.php');  

ini_set('mysql.connect_timeout', -1);
ini_set('default_socket_timeout', -1);

if (!function_exists("GetSQLValueString")) {
 function GetSQLValueString($theValue, $theType,  $TestConnection, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ?  mysqli_real_escape_string($TestConnection, $theValue) :  mysqli_escape_string($TestConnection, $theValue);

switch ($theType) {
 case "text":
   $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
   break;    
 case "long":
 case "int":
   $theValue = ($theValue != "") ? intval($theValue) : "NULL";
   break;
 case "double":
   $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
   break;
 case "date":
   $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
   break;
 case "defined":
   $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
   break;
 }
 return $theValue;
 }
}

$target_url = "***";
$html = new simple_html_dom();
$html_sub_page = new simple_html_dom();
$html->load_file($target_url);

//Declare elements {......}

//Retrieve latest ID from table {....}

//Main Page content {....}

MySQL服务器已经消失（错误2006）有两个主要原因和解决方案：

服务器超时并关闭连接。要修复，请检查my.cnf配置文件中的“wait_timeout”mysql变量是否足够大。
服务器丢弃了错误或过大的数据包。如果mysqld获取的数据包太大或不正确，则会假定客户端出现问题并关闭连接。要修复，您可以增加my.cnf文件中的最大数据包大小限制“max_allowed_packet”，例如。设置max_allowed_packet = 128M，然后sudo /etc/init.d/mysql restart。
