RE: [PHP] REGEX: grouping of alternative patterns

Hey list,

I'm having problems with grouped alternative patterns.
The regex I would like to use, is the following:

/\s*(`?.+`?)\s*int\s*(\(([0-9]+)\))?\s*(unsigned)?\s*(((auto_i
ncrement)?\s*(primary\s*key)?)|((not\s*null)?\s*(default\s*(`.
*`|[0-9]*)?)?))\s*/i

Since all the parts beyond the id and datatype are optional, I don't see how this can ever not match. Please define more accurately what you mean by "doesn't match".

Cheers!

Mike
