patterns provided in the functions above
what the functions do...
search in the text all links and puts bbcode [URL] around the link
example of the form text:
==
bla bla http://domain.tld/something/ more bla bla...
==
submitted form text passed to functions and text must appear on the page like
this:
==
bla bla [URL]http://domain.tld/something/[/URL] more bla bla...
==
but text is removed, submitted form is EMPTY, i mean, nothing to appear
