PHP-PDO错误：在DSN字符串中指定了无效的关键字“host”

Question

Trying to connect to mssql server on smarterasp.net dns but without success so far. Had a prior issue with the drivers. Installed them and they are working perfectly (added them in php.ini)

Using php version:5.6 , added to php.ini the following in order for the php-pdo-mssql to work:

• extension=php_pdo_sqlsrv_56_nts.dll
• extension=php_pdo_sqlsrv_56_ts.dll
• extension=php_sqlsrv_56_nts.dll
• extension=php_sqlsrv_56_ts.dll

What have I done so far on this code:

<?php
 try {
     $conn = new PDO("sqlsrv:host=host_name_string;dbname=database_name_string", "username_string", "password_string");

     // set the PDO error mode to exception
     $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
     echo "Connected successfully"; 
 }
 catch(PDOException $e)
 {
     echo "Connection failed: " . $e->getMessage();
 }

?>

• instead of dbname I have put database, it doesn't work
• instead of dbname I have put Database, it doesn't work
• I have added the port 1433 after the host name example:

"sqlsrv:host=host_name_string,1433;Database=database_name_string"

it doesn't work

• I have added the port 1433 after the host name example in this way

"sqlsrv:host=host_name_string;port=1433;Database=database_name_string"

it doesn't work

I have tested the connection with my SQL sever management studio and the given data (values that I'm using here as parameters are 100% fine)

What are my other options?

Answer 1

the correct format for the connection is:

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

from the manual page: PDO_SQLSRV DSN
