convert 16-byte hex "string" to dec in php

[Sergei Shelukhin]

Hi.
I have a string, 16 bytes long, representing a hex number.
I need to convert it to a number and put it into pgsql database; it
complicates the matters further cause pgsql doesn't support unsigned;
thus I have to subtract "magic" number (half the bigint range) from
the conversion result to put it into pgsql.

Is there any way to achieve this?

You could try this function to convert a very large value from hex to
decimal:

It uses the bcmath arbitrary precision functions.
