Parse just numeric part of a string?

dougdrury

Hello,
I am trying to figure out how to pull out just an address number from a full postal address.

I have an address string: "1672-23 Thomas Lane"
I want to just return "1672-23" out of it.

The address could also be "1000 Jackson Court" or any address.

I need a reg expression function that will pull out the numeric part of any address. I have googled for it for a couple days, but nothing comes back as I need it.

Any ideas?

Thanks,
Doug😕

Well as long as the numbers were always just a string of digits, and maybe a hyphen then just '/[0-9-]+/' would be a match, but you could complicate that up by making sure the hyphen is only between number groups, and optional.

How simple, and consistent will your data be?

Use this:

<?php

$address = "1672-23 Thomas Lane";
$number = explode(" ", $address);

?>

As long as there are no spaces in between the numbers this will work. The numbers will be in: $number[0]

Both of those will work. I am using the regex and it works great. Thanks!

'/[0-9]+(?:-[0-9]+)*/'

That would be the improved regex that if someone put

641- would just capture the 641, and ignore the final dash.

Thought Laserlight might have got in on this one, she's an absolute stormer at brewing up regex's in seconds, takes me ages.

Thanks for the updated RegEx. I have one last thing to add to this...

What if I was working with an address string like this:

$string="1234-12 1st Street";
Will the RegEx above only return 1234-12 and not 1234-121?

$string="1234 1st Street";
Will the RegEx above only return 1234 and not 12341?

I want to ignore any numeric chars after the first <space> character. Can that be done?

Thanks!!! I am currently reading all the online tutorials I can trying to get up to speed on regex on my own, but I have a time crunch on this project.

Thanks again for all your input!!!!!!!!!!!

Er, tried it? It would only match 1234-12. It would stop once it runs out of hyphen-number pairs. A space is not a hyphen or a number.
