LoginTimeout

接続の試行のタイムアウト秒数を指定します。

MultipleActiveResultSets

マルチアクティブ結果セット (MARS) のサポートを無効にするか、明示的に有効にします。

QuotedId

SQL-92 の規則に従った識別子のクォートを使う (1 あるいは TRUE) か、レガシーな Transact-SQL のルールを使う (0 あるいは FALSE) かを指定します。

Server

データベースサーバーの名前を指定します。

TraceFile

データのトレースに使うファイルのパスを指定します。

TraceOn

確立した接続用の ODBC のトレースを有効にする (1 あるいは TRUE) か無効にする (0 あるいは FALSE) かを指定します。

TransactionIsolation

トランザクション隔離レベルを指定します。このオプションに指定できる値は PDO::SQLSRV_TXN_READ_UNCOMMITTED、PDO::SQLSRV_TXN_READ_COMMITTED、 PDO::SQLSRV_TXN_REPEATABLE_READ、PDO::SQLSRV_TXN_SNAPSHOT および PDO::SQLSRV_TXN_SERIALIZABLE のいずれかです。

TrustServerCertificate

自己署名のサーバー証明書をクライアントに信頼させる (1 あるいは TRUE) か させない (0 あるいは FALSE) かを指定します。

WSID

トレース用のコンピューター名を指定します。

例1 PDO_SQLSRV DSN の例

以下の例は、MS SQL Server データベースに接続する方法を示します。

$c = new PDO("sqlsrv:Server=localhost;Database=testdb", "UserName", "Password");

以下の例は、ポートを指定して MS SQL Server データベースに接続する方法を示します。

$c = new PDO("sqlsrv:Server=localhost,1521;Database=testdb", "UserName", "Password");

以下の例は、サーバー ID 12345abcde の SQL Azure データベースに接続する方法を示します。 SQL Azure に PDO で接続するときは、ユーザー名が UserName@12345abcde (UserName@ServerId) となることに注意しましょう。

$c = new PDO("sqlsrv:Server=12345abcde.database.windows.net;Database=testdb", "UserName@12345abcde", "Password");

I finally discovered that sqlsrv and pdo_sqlsrv are not the same thing, and work differently, and have different requirements. As near as I can tell, sqlsrv requires the odbc driver from Microsoft. pdo_sqlsrv does not, it uses pdo. This caused me a lot of grief until I figured this out, as most of the discussion for pdo_sqlsrv seems to relate to sqlsrv, not pdo_sqlsrv. They are not the same.

pecl install sqlsrv

This will download and build the module for sqlsrv-4.3.0.tgz. This will not work without the microsoft ODBC driver, which apparently needs to be downloaded and installed separately. I was never able to get this to work as my distro is not one of the supported distros the Micorosoft builds the ODBC driver for.

pecl install pdo_sqlsrv

This downloads and installs the module for pdo_sqlsrv-4.3.0.tgz. This does NOT require the Microsoft ODBC driver. Why? Because it does not use ODBC, it uses PDO to connect to mssql server.

To make a connection using pdo_sqlsrv (without the Microsoft ODBC driver):

$dbh = new PDO ("dblib:host=<ip address>;dbname=db","user_id","password");

Note that we are using "dblib:host", NOT "sqlsrv:host".

So to clarify: In my case, I'm using PHP 7.2 and I want to connect to a Microsoft sql server database. I'm using Slackware 14.2 64 bit, and Microsoft does not build an ODBC driver that works (at least I could not get it to work) for this distro.

1) Install unixODBC. I had to download the source and ./configure|make|make install, as the version that came with the package manager did not work. Don't be afraid to go outside of your package manager and install unixODBC from scratch.
2) When you configure PHP, be sure to include --with-pdo-odbc=unixODBC
3) After you install PHP, use PECL to download and install pdo_sqlsrv. Do NOT install sqlsrv. And be sure to add extension-pdo_sqlsrv to php.ini if necessary, the PECL installer doesn't always do this.

Now you should be able to to do this:

$dbh = new PDO ("dblib:host=<ip address>;dbname=db","user_id","password");

When I do the steps above, it works great. YMMV. I welcome comments from anyone that knows more about this process.

This is the code that worked for me. I had to specify both the host name [localhost] and the server instance name [SQLEXPRESS], separating them with a double backslash before it would work.

<?php
$conn
= new PDO('sqlsrv:Server=localhost\\SQLEXPRESS;Database=MyDatabase', 'MyUsername', 'MyPassword');
?>

I suspect the problem with "Server=foo-sql\MSSQLSERVER" was you didn't escape the backslash, with a backslash.

If hostname worked, than IP would work as well given a hostname resolves to an IP unless your DNS was mapping to the wrong IP which would be a simple issue.

I suspect you are running your web services on the same host as mssql?  If so, confirm that your mssql server is set to bind to IP addresses (if you want access from the outside of that box).  If you are only able to connect via a name (as in a NetBIOS or Active Directory name), it's likely you are connecting to a "socket" or named pipe.

I found with MS-SQL Server 2008 on Windows Server 2008 R2 that I needed to use the MSSQL Server name. The servers hostname or IP address would not work ( with or without port, and/or SQL instance name, etc.) After trying several combinations, this is what I found worked in my configuration:

host-ip: 10.4.2.50
host-name: mssqlhost.mydomain.org
mssql-server-name: foo-sql
mssql-instance-name: MSSQLSERVER
database-name: mydb

<?php

$dbh
= new PDO("sqlsrv:Server=foo-sql,1433;Database=mydb", $user , $pass);

?>

The above worked with and without port (,1433). I also noticed adding the instance name (MSSQLSERVER) after the server name with a slash (\), as in "Server=foo-sql\MSSQLSERVER" caused a failure to connect.

Adding the backslash solved the problem for me.

Here's my functioning localdb connection string:

new PDO("sqlsrv:Server=(localdb)\\v11.0 ; Database = my_db ; AttachDBFilename = C:\Users\user\my_db.mdf", "", "");
