Question

主要问题是，过去一周我无法让我的脚本运行查询。

我正在运行wamp apache 2.4，php 5.5和mysql 5.6

  if ($flag == true) {

    //try to connect to db with given parameters
    // minimal validation to make sure no input was sent in error so now i can begin code to connect to database 
    // using the pdo php data object extension

    print 'all input validated';

    $host= "127.0.0.1";
    $db_name ="theturnbuckle";
    $port= "3306";
    $dbusername= 'root';
    $dbpassword= '';

    //registration details including host, port and database name
    $dsn = "mysql:host=$host;port=$port;dbname=$db_name;";

    //error handling for connection
    try {
       $db = new PDO($dsn, $dbusername, $dbpassword);
       //if no proplems flag a variable for connection status which is to be used later.
       $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
       $db->setFetchMode(PDO::FETCH_ASSOC);


       //first query to test that the username is not in the database.
       $username = $_POST['username'];
       $userquery = "SELECT username  FROM registation_view WHERE username = :username" ; 


       //second query to test for existing email
       $email = $_POST['email'];
       $emailquery = "SELECT email FROM registation_view WHERE email = :email";

       //preparing statement, binding html input to variables to be used in the prepared statement.
       $db = new PDO($dsn, $dbusername, $dbpassword);
       $stmt = $db->prepare($userquery);
       $stmt->bindParam(':username', $username, PDO::PARAM_STR, 15);

        //execute the query in variable
        $stmt->execute($userquery);
        if ($stmt->fetchColumn() > 0){
            print 'Sorry ' .$username . 'is already in use please try another';
        }//else the username is not is use as fetchColumn is null or the if is false
        else {$registerprocess === true;}


        $db = new PDO($dsn, $dbusername, $dbpassword);  
        $stmt = $db->prepare($emailquery);
        $stmt->bindParam(':email', $email, PDO::PARAM_STR, 15);

        $stmt->execute($emailquery);
         if ($stmt->fetchColumn() > 0){
             print 'Sorry ' .$_POST['email'] . 'is already in use please try another';
             $registerprocess === false;
         }//else the email is not is use as fetchColumn is not > 0 so the registration proceeds.
         else {$registerprocess === true;}

         // catch (PDOException $e){
         //die("Unable to run query: " . $e->getMessage());}


         if ($registerprocess === true) {       
              //username and email are not on record so i am free to INSERT data into database
              $query = "INSERT INTO registration_view (username, password, email, gender, date_of_birth, joindate)
              VALUES (?, ?, ?, ?, ?, ?)";

              $joindate = now();
              $date_of_birth = $_POST['day'] . $_POST['month'] . $_POST['year'];

              $stmt->prepare($query);
              $stmt->bindParam(1, $_POST['username'], PDO::PARAM_STR, 20) ;
              $stmt->bindParam(2, $_POST['password'], PDO::PARAM_STR, 20) ;
              $stmt->bindParam(3, $_POST['email'], PDO::PARAM_STR, 20) ;
              $stmt->bindParam(4, $_POST['gender']) ;
              $stmt->bindParam(5, $date_of_birth) ;
              $stmt->bindParam(6, $joindate) ;

              $stmt->execute();

              print ' Welcome ' .$username . 'you are now registered';
       }
    } catch (PDOException $e) {
        die("Unable to connect: " . $e->getMessage());
    }

}//INPUT VALIDATION IF

这是我的代码，第一个标志是一旦数据验证成功完成那么多工作和打印'验证'就继续;证实了这一点。

我确定$ dsn没有出错，因为之前显示的错误是用单引号括起来的，现在没有显示这样的错误。

虽然我对代码是一团糟，但我也经历了php.ini my.ini和apache.config，但是一周说没有运气。

我可以添加任何帮助（或者至少可能是一个潜在客户）的唯一内容是apache和php错误日志的一些错误。

Apache尝试从本地主机运行脚本时显示此内容。

[Mon Dec 29 12:49:13.855653 2014] [authz_core:error] [pid 3632:tid 964] [client ::1:49206] AH01630: client denied by server configuration: C:/Apache24, referer: http://localhost/theturnbuckle/

并且php显示了这一点，虽然我已经重新安装了apche服务器，因为在安装之前和之后我将php_intl.dll和phpldap.dll移动到了wamp中的另一个文件夹，这些错误消失了。（甚至不确定这是否是最好的做法）

[24-Dec-2014 12:00:37 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll' - The specified module could not be found.

我取消注释了一些mysql服务器变量。

innodb_data_home_dir = C:\mysql\data/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = C:\mysql\data/
innodb_log_arch_dir = C:\mysql\data/

最后我检查了一些php.ini服务器变量来尝试帮助解决问题，显示错误已经开启。

似乎安装了所有php扩展，例如php_pdo_mysql和php_mysqli。

但是在一天结束的时候，我正在黑暗中挣扎。

你有两个警告：

[24-Dec-2014 12:00:37 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll' - The specified module could not be found.

和

[24-Dec-2014 12:00:37 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_ldap.dll' - The specified module could not be found.

所以只需安装或启用这些扩展程序。

获取PDO（或mysqli扩展）以在数据库上运行查询的问题
