help with regex

[Anon]

I'm trying to build a regex to validate a street address, so I need to allow letters, numbers, as well as ".", "-", and single quote " ' ". I need to check for this patter separated by white space, such as 122 Some Street

Here is my attempt:

ereg('(^{[a-zA-Z.0-9-\']+\s{0,1})([a-zA-Z.0-9-\']+\s{0,1})+',$data)}

I get this

Warning: REG_ERANGE: in e:\inetpub\classes\validate.inc on line 39

1. Is there a simpler way
2. If I remove the \' and -, it works, or at least I don't get an error.

Please help.

Thanks,
Brian

I just wrestled with this problem, and I figured out that it has to do with the order that you place special characters in. It's kind of weird...

I got the REG_ERANGE warning with this:

[A-Za-z-$_.]

But I didn't get the error with this:

[A-Za-z\$.-_]

Hope this helps you out!
