写了一个设置pdo DSN的方法想请大家看看
写了一个设置pdo DSN的方法想请大家看看
ORACLE跟SQLITE 都只有数据库主机，连数据库名都没有，我不知道怎么设置。
发出来大家看看吧 private function setDSN()
{
switch (strtoupper($this->datatype)){
case 'MYSQL':
$_DSN = 'mysql:host='.$this->hostname.';dbname='.$this->database.';port='.$this->hostport;
break;
case 'MSSQL':
case 'DB2':
$_DSN = 'dblib:host='.$this->hostname.':'.$this->hostport.';dbname='.$this->database;
break;
case 'ORACLE':
$_tns = "
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP )(HOST = $this->hostname)(PORT = $this->hostport))
)
(CONNECT_DATA =
(SERVICE_NAME = $this->database)
)
)";
$_DSN = 'oci:dbname='.$_tns;
break;
case 'SQLITE':
$_DSN = 'sqlite:'.$this->hostname;
break;
case 'PGSQL':
$_DSN = 'pgsql:host='.$this->hostname.'port='.$this->hostport.';dbname='.$this->database;
break;
case 'FIREBIRD':
$_DSN = 'firebird:dbname='.$this->hostname.':'.$this->database;
break;
case 'ODBC':
$_DSN = 'odbc:DSN='.$this->hostname.';UID='.$this->username.';PWD='.$this->password;
break;
}
return $_DSN;
}
复制代码ORACLE 看了一下cn.php.net上的又修改了一下。

if oracle and oracle instant client has been installed,
without db in the same host
For UNIX/LINUX，set $LD_LIBRARY_PATH
appent your instant client path and client/lib path to it,
For windows set PATH like this
After set the path ,set TNS_ADMIN everioment ,point to
where tnsnames.ora located.
Then,you can use service name to connect to your Database
Test coding
$param = $_POST;
$db_username = "youusername";
$db_password = "yourpassword";
$db = "oci:dbname=yoursid";
$conn = new PDO($db,$db_username,$db_password);
$name = $param['module'];
$file = $param['file'];
$stmt = $conn->exec("INSERT INTO AL_MODULE (AL_MODULENAME, AL_MODULEFILE) VALUES ('$name', '$file')");
?>

If instant client has been installed but the full oracle client
not yet ,you can use pdo to connect to oracle database
like following coding:
$tns = "
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = yourip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
";
$db_username = "youname";
$db_password = "yourpassword";
try{
$conn = new PDO("oci:dbname=".$tns,$db_username,$db_password);
}catch(PDOException $e){
echo ($e->getMessage());
}
?>

1、SQLite不是数据主机，而是数据库文件
2、ORACEL的主机格式可能有多种形式，说不定人家是一个数据集群呢？
