Address extraction from string - php

Question

I've been looking around for some help, but haven't found my solution yet. The problem is a lot like this one: Extract address from string
But I cannot seem to rewrite the php code to solve my problem.
I'm using Magento and I have only 1 address field combining streetname and housenumber. For my CSV export I'm using a XSLT extension, which can work with PHP also. For retrieving the address and importing, I need streetname and housenumber to be 2 strings.
At this moment I'm using:
preg_replace('/[0-9,.]/','',$address);
for retrieving the street,
and:
preg_replace('/[^0-9,.]/','',$address);
for retrieving the housenumber. And... this just doesn't work in a lot of situations. Because sometimes a number is included in the streetname (like 2nd street) or a character is included in the housenumber (like 36-B).
The only 2 things we always know are "A housenumber always includes a number" and "A housenumber (sometimes including characters) is always at the end of the string"
I've made an image of a few examples:

Answer 1

You will have to search for the last number in the string. Than the first space before that, and split it at this position

Answer 2

I found the following code to work almost perfect.
static function addressFix($address){
$r = strrev ($address);
$str1= preg_replace('/^(.*?\d+)(.*?)$/', '$2', $r);
return strrev($str1);
}
static function houseNumberFix($address){
$r = strrev ($address);
$str2= preg_replace('/^(.*?\d+)(.*?)$/', '$1', $r);
return strrev($str2);
}
