excluding parenthesis, space and dashes from phone number

[afan pasalic <afan@xxxxxxxx>]

hi,
I store phone number in mysql as integer, e.g. (123) 456-7890 is stored
as 1234567890.
though, in search form they usually type in a phone number with
parenthesis/space/dashes. I have to extract numbers before I search
through mysql.

currently, I use eregi_replace() function, several times, to do the job:
eregi_replace(' ', '', $phone);
eregi_replace('(', '', $phone);
eregi_replace(')', '', $phone);
eregi_replace('-', '', $phone);
and it works fine.

but, is there any better way? more "fancy"? :)

thanks for any help.
