Your code looks OK, there is nothing that immediately stands out anyway.
So you need to tick off everything is working correctly.
Can you connect successfully to the database (does another query provide the correct results)?
Do the username/password variables hold actual values?
In your login function do both of the queries work and return values?
If you can't debug it at least dump out the variable values and the SQL statements so you confirm what is happening. Run the SQL into against the the database in the command line or similar to make sure that gives you what you would expect to see.

I fixed the issue

issue is my existing password has a empty space on the rightside.

i have used trim function in include/users.php at line 22

$stored_password = $data['SWYQ64PWD'];

to

$stored_password = trim($data['SWYQ64PWD']);
