Php 用PDO（类似表的内容）重写mysql_*

因此，我在从mysql.*函数迁移到类似PDO的语句时遇到了一些问题。我有一个表，其中每行输出一个不同的列。然而，我不确定如何通过PDO实现这一点

        $SQL = "SELECT `id`, `email`, `information`, `type`, `language`, `status` FROM `requests`";
        $exec = mysql_query($SQL, $link);
           while ($row = mysql_fetch_array($exec)){
              echo "<tr class='tg-031e'>";
              echo "<td class='tg-031e'><input type='checkbox' name='checkbox[]' value=" . $row['id'] . "></form></td>";
              echo "<td class='tg-031e'>" . $row['email'] . "</td>";
              echo "<td class='tg-031e'><textarea readonly style='width:470px;height:80px;border:none;resize:none'>" . $row['information'] . "</textarea></td>";
              echo "<td class='tg-031e'>" . $row['type'] . "</td>";
              echo "<td class='tg-031e'>" . $row['language'] . "</td>";
              if(isset($_POST['checkbox'])){
                foreach($_POST['checkbox'] as $update_id){
                  $update_id = (int)$update_id;
                  $qR = "UPDATE requests SET status='✔' WHERE id=$update_id";
                  mysql_query($qR);
                                    header('Refresh: 1; URL=index.php');
                }
              }
        }

要开始使用的简单db类：

<?php 


class db {

    public static $db_host = "";
    public static $db_user = "";
    public static $db_pass = "";
    public static $db_name = "";

    public static function dbFactory() {
        $host = self::$db_host;
        if(strpos($host,":") !==false) {
            $parts = explode(":",$host);
            $hostname = "unix_socket=".$parts[1];
        } else {
            $hostname = "host=$host";
        }
        $user = self::$db_user;
        $pass = self::$db_pass;
        $dbase = self::$db_name;        
        $pdo = new PDO("mysql:$hostname;dbname=$dbase", $user, $pass);
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);        
        return $pdo;
    }
}

$id = 115;

$pdo = db::dbFactory();
$stmt = $pdo->prepare("SELECT * FROM `tablename` WHERE `id` = :id ");
$stmt->bindValue(':id', $id, PDO::PARAM_INT);
$stmt->execute();
$res = $stmt->fetchAll(PDO::FETCH_ASSOC);

print_r($res);

对不起，这与问题有什么关系？@schmitsz上面的代码为OP提供了一个示例，说明如何开始使用pdo，并获取一个包含查询结果的数组。似乎是这样的，它可以给OP一个如何重写代码的想法。也许我误解了什么，但在给定的示例中，OP执行了一个
获取数组
。我向他展示了一种使用pdo将所有结果获取到数组的方法。这可以用来重写给定的代码。
<?php 


class db {

    public static $db_host = "";
    public static $db_user = "";
    public static $db_pass = "";
    public static $db_name = "";

    public static function dbFactory() {
        $host = self::$db_host;
        if(strpos($host,":") !==false) {
            $parts = explode(":",$host);
            $hostname = "unix_socket=".$parts[1];
        } else {
            $hostname = "host=$host";
        }
        $user = self::$db_user;
        $pass = self::$db_pass;
        $dbase = self::$db_name;        
        $pdo = new PDO("mysql:$hostname;dbname=$dbase", $user, $pass);
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);        
        return $pdo;
    }
}

$id = 115;

$pdo = db::dbFactory();
$stmt = $pdo->prepare("SELECT * FROM `tablename` WHERE `id` = :id ");
$stmt->bindValue(':id', $id, PDO::PARAM_INT);
$stmt->execute();
$res = $stmt->fetchAll(PDO::FETCH_ASSOC);

print_r($res);
