Regular Expression Details

Title Test Find Pattern Title
Expression
\b(((\S+)?)(@|mailto\:|(news|(ht|f)tp(s?))\://)\S+)\b
Description
Whilst writing a plain-text to HTML function, I ran into the problem of links that users had written with <a> tags (as opposed to just writing the URL) were linking improperly. This regular expression returns many types of URL, and preceding characters, if any. This allows you to handle each type of match appropriately
Matches
href='http://www.deepart.org' | demogorgon@deepart.org | ftp://123.123.123.123
Non-Matches
www.deepart.org | deepart.org | 123.123.123.123

Source The concept of (ht|f)tp(s?) came from, I believe, TwoGuysFromRolla. The rest is yours truly.
