Address Parser is a library that can parse most dutch addresses.
$parser = new \TreeHouse\AddressParser\AddressParser();
$result = $parser->parse('Willembuytechweg 45');
var_dump($result);
The above example will output:
array(3) {
'street' =>
string(16) "Willembuytechweg"
'number' =>
string(2) "45"
'address' =>
string(19) "Willembuytechweg 45"
}
