Separate street name from street number [closed]

Question

I am trying to separate street names from street numbers which have these patterns:

1. "street 12" --- name:street , number:12
2. "street12" --- name:street , number:12
3. "street 12a" --- name:street , number:12a
4. "street12a" --- name:street , number:12a

What is the regex to get the street name, and the regex to get the street number in php and python?

Note: The number is always after the street name so I guess that should shorten it.

Thanks.

Answer 1

I would suggest that the best way to determine when the number starts is when you hit a digit. Thus, you would use

preg_match('/^([^\d]*[^\d\s]) *(\d.*)$/', $address, $match)

Examples:

'Bubbletown 145' => 'Bubbletown', '145'
'Circlet56a' => 'Circle', '56a'
'Bloomfield Avenue 68' => 'Bloomfield Avenue', '68'
'Quibbit Ave       999a' => 'Quibbit Ave', '999a'
'Singletown551abc' => 'Singletown', '551abc'

It will probably be best for you to consider how you want edge cases to be handled, then write a unit test to test your own Regex function.
