SQLSRV_FETCH_ARRAY in PHP Only Returning 1 Row then stopping
I'm new to the sqlsrv system, been using the mssql system for a while and never had issues. I'm modifying the old mssql to sqlsrv and I'm only getting one row returned in my while loop. When I run the query directly into my SQL Server Management I get 33 rows. You can see, when I run the sqlsrv_num_rows I also get the count of 33 but the fetch is dying after 1 row. I'm connecting to my DB inside the db_conx.php file which is included at the top of this page.
Please advise
Here is what I'm getting on my page:

Dave,
I figured it out... I changed the variable and it worked.
Thanks a lot, this has been driving me crazy. I'm used to in MYSQL and MSSQL to be able to just change the DB and not have to redo the connection string.

Actually that would not have worked in either one of those drivers inside a loop. You could change the database when you have used up the data but you could never have re-used it inside a loop like that.

Dave,
The old way I was doing I was using the mssql_select_db and changing it back and forth inside the while loop and it still worked fine.

There is a lot of code that is not in your post above. Anything that overwrites the results from the first query will kill the 'while' loop. And there is a good chance that the 'sqlsrv' driver handles things differently than the 'mssql' driver. For example, the database selection is part of the basic connection string in 'sqlsrv' and not a separate statement or command like it is with 'mysql' or 'mssql'. http://php.net/manual/en/function.sqlsrv-connect.php And in the newer 'mysqli' driver, the database selection is also part of the connection command. http://php.net/manual/en/mysqli.construct.php

Thanks Dave. I'm learning that all this is different and so not knowing and asking is how to learn. Yes, there is a lot of code not in my example here, but this was the basis of me trying to get information at a basic level then expanding. There was no reason to post ALL 200+ lines of code when the first 80 lines is where my main problem was.
Thanks a lot for the information and guidance.

That's fine, it wasn't a complaint. Yes, the drivers and methods have changed. Thanks for the points.

How do I change the database that I'm querying then? I'm using an attendance_db in the first part then bblearn in the second.
