Arduino UPDATE Mysql

[Darci CIdade]

Dear,

I need the Arduino make UPDATE in the database, for example:

When input HIGH the arduino, arduino send number 1 to the database.
When input LOW the arduino, arduino send number 0 to the database.

Need php program to make this change in mysql or is to make direct connection Arduino -> Database?

Every connection between Arduino and database is OK and running.

Thanks.
