                Using other regular experssions from this page, combining others for email addresses, and mixing in my own ideas - I came up with this regular expression.  Can be used to validate input into a database.  |

nice pattern
if you want to match some web pages like example.com
then i would add as well smth from myself
(((https?|ftp)\://|)((\[?(\d{1,3}\.){3}\d{1,3}\]?)|(([-a-zA-Z0-9]+\.)+[a-zA-Z]{2,4}))(\:\d+)?(/[-a-zA-Z0-9._?,'+&%$#=~\\]+)*/?)
