Saving file from database without user

[Thierry]

I got a table with a large amount of base64 encoded word document in a MSSQL text field.
I can open them fine with PHP and no problem there, but I need to find a way to open all that base64 decoded mesh and save it to a word document in a folder WITHOUT user interference, so in the background.
I havent found a way yet to save it in the background, all the base64 decoded mesh cant seem to be saved just like that.
If word could open that mesh, then save it somewhere in the background, that be great.

Any ideas?

(javascript or PHP will do fine either way as I am using both)
