Valid UK telephone regex with extensions

I need a regex for php that allows 0-9, the string ext, spaces and + (for UK telephone numbers, ext is for extension). here is my attempt which doesn't work:

/^[\d -(ext)]+$/

Any ideas?

You need to take the string out of the character class:

/^([\d -]+|ext)+$/

To allow ext just once:

/^[\d -]+(ext)?[\d -]+$/
