如果一个PHP脚本突然不起作用怎么办

我有这个登录代码，昨天晚上睡觉前工作。没有人使用我的电脑。但今天早上突然停止工作。我的其他代码也无法正常工作。事实上，我确信在我离开他们之前他们都在工作。我重新格式化了我的硬盘。我有一个工作项目的备份。我不明白为什么它不起作用。任何人都经历过这个？如果一个PHP脚本突然不起作用怎么办

<?php 




include('conn.php'); 








     $uname = mysql_real_escape_string($_POST['yname']); 
     $pword = $_POST['pword']; 
     $pwordmd5=md5($pword); 



     $result = query_database("SELECT * FROM admin_table WHERE Uneym = '$uname' AND Pwerd = '$pwordmd5'", "onstor", $link); 
     $num_rows = mysql_num_rows($result); 



     if ($result) { 
      if ($num_rows > 0) { 
       session_start(); 
       $_SESSION['loginAdmin'] = "1"; 



       //added feb 5 2011 

       $_SESSION['Uneym'] = $uname; 






       query_database("UPDATE admin_table SET Current='1' WHERE Uneym = '$uname' AND Pwerd = '$pwordmd5'", "onstor", $link); 



        header ("Location: adminpage.php"); 


      } 



      else { 
       session_start(); 
       $_SESSION['loginAdmin'] = ""; 
       header ("Location: ../login.php"); 
      } 
     } 
     else { 
      $errorMessage = "Error logging on, please try again."; 
     } 











?>

我有这个PHP的错误日志：

这里的conn.php正在被指出的错误日志：

<?php 



function open_connection($host, $user, $password){ 
    return mysql_connect($host, $user, $password); 

} 

function close_connection($link){ 
    return mysql_close($link); 

} 

function query_database($query, $database, $link){ 
    mysql_select_db($database, $link); 
    return mysql_query($query, $link); 
} 

function fetcher($result){ 
    return mysql_fetch_assoc($result); 

} 

function query_checker($query){ 
    if(!$query){ 
    echo "error!".mysql_error(); 
} 
    return mysql_error(); 

} 

$link=open_connection('localhost','root', '1234'); 
?>

而且没有修改康涅狄格州。 php，因为它是你想连接数据库时应该写的第一个脚本。还有一件事，在我重新格式化之前，整个项目只有一个C盘。现在我在x驱动器上。我不确定这是否是问题。

听起来像服务器没有响应或连接被阻止。你有没有检查过，MySQL服务器正在运行？ – 2011-02-13 00:31:17

是的，我重新启动了wampserver的所有服务。甚至试图重新启动mysql服务。我什至不能访问phpmyadmin – 2011-02-13 00:33:17
