2d multidimensional array to 1d array in php

Question

Just wondering if anyone has transformed a 2 dim array to a one dim array in php. I\'ve yet to come across a clear explanation in php. Any suggestion would be appreciated.

Answer 1

It depends on what you need but if you want to reduce your 2d array to a 1d curve that completley fills the 2d plane you probably looking for a spatial index or a space-filling-curve. There are some famous and not so known like the z-curve, the hilbert curve, the peano curve or the moore curve. You can write such a curve with a L-system.
