No error is reported - neitehr stsmt nor mysqli objects - database is simply not updated.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Sorry, but this is not correct.
Had a lot of problems with the database, but this issue is solved.
Somebody used $string[$idx]='' to remove start and finishing quotes from the string sent to database.
Doesn't show up when string is printed on screen, but the "null-characters" are still there - in the string in php and also in the data stored in the database.
So everything is actually functioning as intended - just not as expected, and it doesn't look right.

Very sorry for the inconvenience.
