Decrptying

[bookerb6]

Hey guys.Its my first time trying to decrypt.I have numbers that I must decrypt.

Here is the riddle.

<?phph>
Here it [e-mail] = [e-mail] which will lead you to 171225.13916.co.za

<?>

I did the second part.which traslates to mip m = 12, i = 9, p = 16.But unfortunately, the same concept does not apply to 171225.
Thanks alot guys.
