My database table holds phone numbers that may contain characters other than digits (that's not a problem in itself).
I want to be able to apply a regular expression (to ignore all characters except digits) to the attribute 'phone' first
andthen for the ILIKE to compare
the result to $telephone. I can't find any way of applying the RE to phone.
My current query without the RE is as follows:
SELECT telephone
FROM addresses
WHERE id = user_id
AND phone ILIKE '%".addslashes($telephone)."%'"
I want to do something like: AND phone([^[:digit:]]) ILIKE $telephone
But this doesn't work.
Any ideas?

You can use function translate
