这是我正在使用的PHP代码。我必须使用mb_convert_encoding()，这是PHP“ Multibyte String”（“ mbstring”）扩展名的一部分。
代码：
<?PHP
// NB: save this PHP script as an ANSI text file, not a UTF-8 encoded file
$dbh = new PDO(
'odbc:Driver={Microsoft Access Driver (*.mdb)};' .
'Dbq=C:\\Users\\Public\\acc2000.mdb;' .
'Uid=Admin;Pwd=;');
// this is our test case
$city = 'Montr茅al';
echo '$city: ' . $city . "\r\n";
// this is the UTF-8 "token" we'd get from the AJAX call...
$token = utf8_encode($city);
echo '$token: ' . $token . "\r\n";
// ...and here we convert to the Access_2000 character set
$win_token = mb_convert_encoding($token, 'Windows-1252', 'UTF-8');
echo '$win_token: ' . $win_token . "\r\n";
$sth = $dbh->prepare('SELECT * FROM Cities WHERE City = ?');
$sth->Execute(array($win_token));
$rst = $sth->fetchAll();
echo '$rst: ';
print_r($rst);
从Windows命令行运行时的结果：
C:\__tmp>\PHP\PHP odbcTest.PHP
$city: Montr螛al
$token: Montr鈹溾寪al
$win_token: Montr螛al
$rst: Array
(
[0] => Array
(
[City] => Montr螛al
[0] => Montr螛al
)
)
