SQLSTATE [HY000] [2002]错误

标签: php mysql csv

我目前正在尝试将CS​​V文件中的数据插入到我的mysql数据库中。表格和所有功能都正常工作,因为我已经过测试以确保它正在读取文件等。当我准备将PDO插入到mysql中时,我在Chrome中没有错误。现在,当我在Chrome(任何浏览器)中出现服务器错误时,我发现它execute(),我查看了我的错误日志文件,其中显示了函数所在的位置:

SQLSTATE[HY000] [2002] 
   No connection could be made because the target machine actively refused it.

我会将代码粘贴到我所做的功能上 代码:

function returnBack(){

    header("Location:csvuploader/csvuploaderform.php?seterror=1");
    exit;

}

if (isset($_POST['submit'])){

    /*******************************CHECK TO MAKE SURE FORM IS PROPERLY FILLED AND GET NAME OF COLUMNS IN CSV FILE *********************************************************/
    if (empty($_FILES['file'] ) )
    {
        returnBack();

    } 
    if (empty($_POST['firstname'])){
        echo "firstname is empty";

        returnBack();
    }
    if (empty($_POST['lastname'])){
        echo "lastname is empty";

        returnBack();
    }if (empty($_POST['email'])){
        echo "email is empty";

        returnBack();
    }
    if (empty($_POST['phone'])){

        returnBack();
    }

    $file = $_FILES['file']['tmp_name'];    

    $handle = fopen($file , "r");

    $fileop = fgetcsv($handle,1000,",");

    $fileop=array_map("strtoupper",array_map("trim",$fileop));

    $firstname_index = array_search(strtoupper($_POST["firstname"]),$fileop);
    if ($firstname_index===false){
        returnBack();
    }
    $lastname_index = array_search(strtoupper($_POST['lastname']),$fileop);
    if ($lastname_index===false){

        returnBack();
    }
    $email_index = array_search(strtoupper($_POST['email']),$fileop);
    if ($email_index===false){

        returnBack();
    }
    $phone_index = array_search(strtoupper($_POST['phone']),$fileop);
    if ($phone_index===false){

        returnBack();
    }
    /***********************ASSIGN COLUMN VALUES TO ACCORDING VARIABLES AND INSERT THEM INTO CSV TABLE IN DB *************************************/
    try {  
  # MySQL with PDO_MYSQL  
  $DBH = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);  
  $DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

    }  
    catch(PDOException $e) { 
        echo "I'm sorry, I'm afraid I can't do that.";  
        file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);   
    }
    /*$fileop = fgetcsv($handle,1000,",")*/
    while (($fileop=fgetcsv($handle)) !== false)
    {

        $fileop=array_map("trim",$fileop);

        $firstname = $fileop[$firstname_index];

        $lastname = $fileop[$lastname_index];

        $email = $fileop[$email_index];

        $phone = $fileop[$phone_index];


        $insertdata = $DBH->prepare("INSERT INTO csvdata (firstname, lastname, email, phone) VALUES ('$firstname','$lastname','$email','$phone')");
        //var_dump($insertdata);

        $insertdata->execute();


    }

}


$DBH = null;

UPDATED ------------------------------------- Heres some info

PHP信息 - PHP Version 5.3.10, System Windows NT W03 6.0 build 6002 (Windows Server 2008 Standard Edition Service Pack 2) i586

更新------------------------------------

我能够连接到MySQL服务器并浏览它 - 插入我所做的其他功能的数据,它们都完美无缺。只是这个人会给我一个错误。

更新---------------------------------------------- ---------------------------

想出你们所有人的帮助。我实际上需要填写所有数据列才能使用。例如我有(名字,姓氏,电子邮件,电话)我需要填写用户名,密码,状态部分。谢谢你们的帮助!希望这能帮助任何陷入同一个洞的人!

while (($fileop=fgetcsv($handle)) !== false)
{

    $fileop=array_map("trim",$fileop);

    $firstname = $fileop[$firstname_index];

    $lastname = $fileop[$lastname_index];

    $email = $fileop[$email_index];

    $phone = $fileop[$phone_index];

    $csvusername = $firstname . $lastname;

    $csvpasswordname = $lastname . $firstname;

    $status = "Open";




    $sth = $DBH->prepare("INSERT INTO csvdata (firstname, lastname, email, phone, username, password, status, memberview) VALUES (?,?,?,?,?,?,?,?)"); 
    $sth->execute(array($firstname, $lastname, $email, $phone, $csvusername, $csvpasswordname, $status, $memberview));

}

不一定是您的问题的一部分,但您使用的是准备好的状态错误。使用准备好的语句的PArt是这样的,DB负责db特定的转义。为此,您使用占位符编写查询,然后将其替换为传递给语句的值。所以在这种情况下:

$insertdata = $DBH->prepare("INSERT INTO csvdata (firstname, lastname, email, phone) VALUES (?,?,?,?)"); 
$insertdata->execute(array($firstname,$lastname,$email,$phone));

或者使用更稳健的命名占位符:

$insertdata = $DBH->prepare("INSERT INTO csvdata (firstname, lastname, email, phone) VALUES (:firstname, :lastname, :email, :phone)"); 
$insertdata->execute(array(
  ':firstname' => $firstname,
  ':lastname' => $lastname,
  ':email' => $email,
  ':phone' => $phone
));

现在,只要您的错误ID愿意打赌您使用localhost作为主机名,这可能会导致Windows上出现问题 - 请尝试使用127.0.0.1。例如:

$DBH = new PDO("mysql:host=127.0.0.1;dbname=the_db_name", $username, $password);
