无法使用PDO连接到Oracle

问题描述

我有这些代码段，但仍然无法连接到Oracle DB.我相信我做对了所有事情，但是我不知道陷阱在哪里.

I have these snippets but I still cannot connect to my Oracle DB. I believe I did everything right but i don't know where the pitfall is.

try {
    $user='weltesadmin'; // Enter your DB User Name.
    $pass='weltespass'; // Enter your DB Password.
    $dataBaseName='weltes'; // Enter your Database Name.
    $dbh = new PDO('OCI:dbname='.$dataBaseName.'charset=UTF-8', $user,$pass);
    echo "Connection Successful";
} catch (PDOException $e) {
    print "Error!: " . $e->getMessage() . " ";
    die();
}

在php.ini上:

extension=php_openssl.dll
;extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll
extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
;extension=php_pdo_pgsql.dll
extension=php_pdo_sqlite.dll
;extension=php_pdo_sqlite_external.dll
;extension=php_pgsql.dll
;extension=php_pspell.dll
;extension=php_shmop.dll

推荐答案

检查已安装的驱动程序，并查看是否已安装oci:

Check your installed drivers and see if oci is installed:

foreach(PDO::getAvailableDrivers() as $driver)
    echo $driver, '\n';

如果未显示oci，则需要安装它( http ://php.net/manual/en/ref.pdo-oci.php )

If oci don't shown, then need to install it (http://php.net/manual/en/ref.pdo-oci.php)
