php - 如何在PDO中设置字符集

Question

我在 pdo 中设置字符集时遇到一些问题。下面是我的连接代码:-

private function Connect()
{
    $this->settings = parse_ini_file("settings.ini.php");
    //$dsn = 'mysql:dbname='.$this->settings["dbname"].';host='.$this->settings["host"].'';
    $dsn = 'mysql:dbname=' . $this->settings["dbname"] . ';host=' . $this->settings["host"] .';charset=utf8'. ';connect_timeout=15';
    try 
    {       
        # Read settings from INI file, set UTF8
        $this->pdo = new PDO($dsn, $this->settings["user"], $this->settings["password"], array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));

        # We can now log any exceptions on Fatal error. 
        $this->pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        # Disable emulation of prepared statements, use REAL prepared statements instead.
        $this->pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

        # Connection succeeded, set the boolean to true.
        $this->bConnected = true;
    }
    catch (PDOException $e) 
    {
        # Write into log
        echo $this->ExceptionLog($e->getMessage());
        die();
    }
}

我将法语字符插入为céréales，但它在数据库中存储为céréales。有人知道如何在pdo中将字符集设置为utf8吗？

Answer 1

您已在连接字符串中设置 utf8 字符集。您不必发送另一个查询，例如“SET NAMES 'uft8'”。

您只需确保:

• Mysql表和字段都是utf8(如uft8_general_ci)

• 输入数据为utf-8

array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8") 也没用。这是设置所有参数的更快方法:

$this->pdo = new PDO('mysql:host='.$this->settings["host"].';dbname='.$this->settings["dbname"].';
      charset=utf8;connect_timeout=15', $this->settings["user"], $this->settings["password"], 
      array(PDO::ATTR_EMULATE_PREPARES => false, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
