Unable to connect to SQL Server with PHP

Question

Connection to sqlsrv string not working.

$login = new PDO("sqlsrv:server=MYSQLSERVER\SQLEXPRESS;Database=db_name", "user", "passw");

And i have error message: Fatal error: Invalid handle returned .

I'm 101% sure that login details is OK. Because it works on other projects. Could be a problem PHP 7 ?

Answer 1

Try "ConnectionPooling=0" in DSN.

sometimes working and sometimes return error

It might be a problem on re-using connection.

DSN Reference: https://msdn.microsoft.com/en-us/library/ff628167(v=sql.105).aspx

There's a problem with PHP Sql Server driver
You should update it to new version

As you mentioned you are using windows, this version is fully working on windows

Answer 3

Looks like to connect to MS-SQL, you will need to utilize ODBC.

Reference: http://php.net/manual/en/pdo.construct.php#120705

$odbc="odbc:Driver={SQL Server};Server=$server;Database=$database;";

$cnx = new PDO( $odbc , $user, $password);

Answer 4
