Question

您好我在PDO连接上显示重音符号时遇到问题。我正在学习php开发web，我开始使用mysql旧的php连接开发

function db_connect()
{
   $result = new mysqli('localhost', 'database', 'password', 'user'); 
   if (!$result)
     return false;
   return $result;
}

我的表使用latin1和utf8字符集，网页工作正常，显示带重音的单词。

我知道charset和collation是好的，因为它以旧方式工作。但是当我尝试使用PDO时，带有重音的所有单词都会有所不同。以下是选择类别名称

的示例

$db = database_connect();
$query = " select xxx from yyy where xxxyid = :xxxyid ";  
$query_params = array( 
    ':xxxyid' => $xxxyid
    );
// Execute the query against the database 
$query = $db->prepare($query);
$result = $query->execute($query_params); 
if (!$result) 
  trigger_error('Query failed: ' . mysql_error(), E_USER_ERROR); 
$num_xxx = $query->rowCount();
if ($num_xxxs == 0)
  return false;  
$row = $query->fetch();
return $row['name'];

我的连接以这种方式设置

$db_options = array( 
    PDO::ATTR_EMULATE_PREPARES => false                     // important! use actual prepared statements (default: emulate prepared statements) 
    , PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION           // throw exceptions on errors (default: stay silent) 
    , PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC      // fetch associative arrays (default: mixed arrays) 
); 
$database = new PDO('mysql:host=server;dbname=dbname;charset=utf8', 'user', 'password', $db_options);    // important! specify the character encoding in the DSN string, don't use SET NAMES
// create prepared statement with one parameter for the category ID

我试图找到一种方法来显示带重音的字母，但我无法解决它。

我的解决方案完全不同。没有PDO的任何新选项等等....我的问题是当我通过phpadmin或脚本填写db的值时，总是存在这种问题。但是当我在电子表格软件中填充db表然后将填充的文件导入db时，问题就解决了。这种知识花了我一天的生命。希望能帮助到你。对不起我的英语，我是斯洛伐克人。
