This is strange

I am a little lost and need your help due to an unknown package which I got a couple of days ago, as I am pretty clueless where the package came from. And ‘clueless’ in that case means that I absolutely have no clue where it came from as I don’t know the sender.

The package came inside a box of the USPS straight from the States and arrived just in time for my birthday which happened to happen at the 17th of this month. Inside the shipping box there was a smaller box which obviously was handcrafted, done with quite some patience and love by a computer geek as the code written on it shows.

This code passage, which seems to be PHP (?) tells, that the package should not be opened before the 17th of this month.

Knowing my address and birthday, I would guess that the package didn’t came ‘by accident’ - and so does the card shipped with it. But sadly I have some little problems reading parts of it (Could someone translate that for me, please?).

Even if I don’t know the sender yet, I am very happy and want to thank that someone thinking of me.
