I'm using a regular expression to split Dutch street, house number and addition from an address. The addition should be optional.
preg_match('/(?P<address>[^\d]+) (?P<number>[\d]+)(?P<numberAdd>[^\d]+)/', $input, $matches)
This only works if the $input is for example Street 1A. But not if the input is only Street 1 (without addition).
So how can I split the address with the addition as optional? The addition may not contain numbers.
Have a try with:
preg_match('/(?P<address>\D+) (?P<number>\d+)(?P<numberAdd>\D*)/', $input, $matches)
