MySql服务器已经走了 - PHP

-1

我是抓取网页内容的初学者。我试图从另一个网站检索内容。所以写了履带的代码。成功抓取另一个网页上的内容。我试图存储所有从其他网站爬行的数据。MySql服务器已经走了 - PHP

我得到“MySql服务器已经消失”错误。任何人都可以帮助我找出我的错误？

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');

    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; 
} 

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

错误是什么？ –

var_dump（$ insertSQL）就在你插入之前.. – MaggsWeb

为什么你从mysqli_切换到mysql_的错误信息？坚持mysqli_。虽然，mysqli_error()需要db句柄作为第一个参数，所以你不能在你拥有的内容中使用它。相反，使用mysqli_connect_error()，因为这不需要数据库句柄。

为什么你检查mysql_real...函数存在，然后使用mysqli_real..函数..？

我已经改变我的代码为“$ TestConnection = mysqli_connect（$ hostname_TestConnection，$ username_TestConnection，$ password_TestConnection）或trigger_error（mysqli_connect_error（），E_USER_ERROR）;” –

现在我检查我的连接状态。连接建立成功。然后更改为“$ Result1 = mysqli_query（$ TestConnection，$ insertSQL）或die（mysqli_error（$ TestConnection））;” （在index.php中）。现在我得到的错误是：MySql服务器走了。 –

这就是因为yopu在你的测试失败的错误中使用了一个变量。你不能在$ testConnection =的'else'中使用$ testConnection – MaggsWeb
