Hey-ho wayfarer! Here is some assembly i did, you may find it useful in your php.ini file :)
[sqlsrv]
; By default, the SQLSRV driver treats warnings as errors;
; a call to a sqlsrv function that generates
; an error or a warning returns false.
sqlsrv.WarningsReturnAsErrors = 1
; By default, errors and warnings that are generated by
; the Microsoft Drivers for PHP for SQL Server are not logged
; LogSubsystems can be one of the following values:
; -1 - Turns on logging of all subsystems.
; 0 - Turns logging off (This is the default).
; 1 - Turns on logging of initialization activity.
; 2 - Turns on logging of connection activity.
; 4 - Turns on logging of statement activity.
; 8 - Turns on logging of error functions activity (such as handle_error and handle_warning).
; These values may be combined with logical OR,
; for example, 6 - connection + statement
sqlsrv.LogSubsystems = -1
; LogSeverity can be one of the following values
; (LOGGING ACTIVITY USING THE PDO_SQLSRV DRIVER):
; -1 - Specifies that errors, warnings, and notices are logged.
; 0 - Logging is disabled (This is the default).

; 2 - Specifies that warnings are logged.
; 4 - Specifies that notices are logged.

; These values may be combined with logical OR,
; for example, 3 - errors + warnings
sqlsrv.LogSeverity = 1
