I wrote a method to set up pdo DSN and would like everyone to take a look

Both ORACLE and SQLITE only have the database host, not even the database name. I don't know how to set it up.
Send it out for everyone to take a look at 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;

}

Copy the code ORACLE and check it on cn.php.net and modify it.

The reason for the low score? Why no one responded`

Saw it

I have never used these two databases

Learn it, only look at the program ideas, not the database used

Please check the relevant information in the manual
Example#1 PDO_SQLITE DSN examples

The following examples show PDO_SQLITE DSN for connecting to SQLite databases: sqlite:/opt/databases/mydb.sq3

sqlite::memory:

sqlite2:/opt/databases/mydb.sq2

sqlite2::memory:

if oracle and oracle instant client has been installed,
without db in the same host

For UNIX/LINUX, set $LD_LIBRARY_PATH
append 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());

}

?>

Copy code
1. SQLite is not a data host, but a database file
2. ORACEL’s host format may have many forms. Maybe it is a data cluster?
