Php ：ERR\u CONNECTION\u CLOSED连接意外关闭

php mysql

Php ：ERR\u CONNECTION\u CLOSED连接意外关闭,php,mysql,connection,Php,Mysql,Connection,我在php中遇到了这个错误…我不知道为什么以下是如何建立我的连接： <?php $hostname_QASite = "localhost"; $database_QASite = "qasite"; $username_QASite = "root"; $password_QASite = ""; $QASite = mysql_pconnect($hostname_QASite, $username_QASite, $password_QASite) or trigger_erro

我在php中遇到了这个错误…我不知道为什么

以下是如何建立我的连接：

<?php

$hostname_QASite = "localhost";
$database_QASite = "qasite";
$username_QASite = "root";
$password_QASite = "";
$QASite = mysql_pconnect($hostname_QASite, $username_QASite, $password_QASite) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

然后我迭代了一行\u获取\u所有\u主题

代码中有什么错误

编辑：

当我尝试在数据库中的不同结果上循环两次时，就会出现这个错误

更新：

这是来自mysql，还是你从Google Chrome收到的

ERR\u CONNECTION\u CLOSED

消息？firefox提供了一个空白页面，但它本不应该出现。我认为这与浏览器无关。如果你在每个iTreation上都回显，会发生什么？我发现了错误，我有一个典型的错误。不是$mysql\u查询，而是需要mysql\u查询
