I have hung up my PDO connection and error code to help you solve the problem. thank you very much.
$ Dbh = new PDO ('mssql: host = localhost; dbname = mydata', 'sa ',' ***** '); // The password is hidden.
This code cannot be connected. the error message is:
'Sqlstate [01002] Unable to connect: SQL Server is unavailable or does not exist. Access denied. (severity 9 )'

Thank you. the connection is successful.
I found the problem. when mssql_connect is used, the servername cannot be localhost or 127.0.0.1. if this is used, the server cannot be found. just change it to the computer name. I am dizzy, and I am delayed for a long time.
