Convert 8 bytes to a signed long (64 bit)

Question

I'm reading 8 bytes from a socket in PHP, and want to transform them into a 64 bit signed integer.

How can I do this in 64 bit PHP? unpack doesn't support 64 bit numbers
In 32 bit PHP, is there a way to make it into a string that can be used by BCMath?
