What sort of function would I need if I wanted to convert those URLs
from plain jane text?

If you have short php tags enabled, assuming you put the url in a
variable called $url...
otherwise...
or a myriad of other ways...
Depending if there are any special characters involved, there are a
couple functions that would be useful for preparing the url before
outputing it in html, but I don't remember them off the top of my
head. RTFM for that.

Right... you do realize that you validate the HTML output of the
executed PHP script, not the PHP script itself. All you really did
was just show another way to skin the same cat. Get over yourself.
As for your "more elaborate example", I'm sure that heredoc will
validate nicely. It also wouldn't hurt to read a book on algorithms
and rethink your code so you aren't processing the same data over and
over again. I "see this kind of slop all over."

Touché!
Would you believe that's on my todo list?

Perhaps you haven't met a few good friends of mine. Their names are
html, head, and body. So what crawled up your backside while you were
reading my example?

The html, head and body elements are all there. They are
mandatory. The tags however, are optional.

No, it's dirty too.

Same as previously. What about .info, .museum and so on tld ? The
filter_var is well suited for this kind of job. Oh, and your regex isn't
smart (you use the case insensitivity flag, but seek A-Z characters...) :D

Blah blah blah.
I've used this code for about 6 years now and have yet to find emails =
that
it didn't work for. If someone has some funky (whacky) RFC extremity, =
then
so be it. That's their problem. Most people have NORMAL emails that =
follow
the above.
But you are correct, I have revised it to be a little more forgiving of =
some
allowed characters...
preg_replace("/([\w\.\-_]+@[\w\.\-_]+\.\w{2,6})/i",

What about them? It's going to depend on how/where you use this. In my =
case,
2 and 3 letter domains are all I encounter. It's trivial to make it =
{2,6} if
you really are going to encounter a .museum domain. DOUBTFUL, but sure, =
I'll
concede the three extra letters. ;-)
However, you point out a few edge cases and so I optimized mine and now =
use
this one:

When I encounter a website the rejects my email address for being =20

I faced a professionnal issue because of a lazy programmer (a Delphi
component that was not aware about "Toto man"@example.com). What you
consider normal e'mail is a subset that is not interoperable. And I hate
that.

You can revised your regex to fit to the new kind of email. But it is
smarter to use the right tool (like filter_vars).
Yeah, I know, I feel like some spanish windmill hunter.
