You're looking in the wrong place. This has nothing to do with PHP -
it's all part of the HTTP protocol.

I think you'll find that's happening in your browser or whatever s handling
your http; iits replacing what it considers illegal characters (which those
are) to an underscore. If yuo actually want a space in a URL you have to
code it as %20 and so on.

What makes you think a dot (which is what the OP is talking about, not a
space) would be illegal in the query part of a URI? It's not even
required to escape it, you can write it as-is. And no browser changes
any char to an underscore, as this would corrupt the data. The reason
here is PHP itself.

Many thanks, this is exactly what I was looking for!
(it's a shame that others would provide false answers with such a
assurance, I nearly went on a wild goose chase there, in HTTP or
Firefox docs)
(OTOH of course no one owes me anything, and any tip is appreciated)
(but if it's not an *answer* but rather a *tip* or general feeling,
it's probably better to make it look that way)
(oops, not wanting to start a flamewar, thanks to all, and peace on
earth to all men of goodwill)

You might be right in retrospect; I do recall that changing several years
ago to where multiple dots were allowed. My mistake.
But both IE8 and FF will change a space to %20; I just tried it again. My
site.com turns into my%20site.com. It happens with a lot of other characters
too changing to their value instead of symbol.

That's correct, because some characters like spaces for example are not
allowed in any part of a URI, so they have to be encoded.

Exactly. Perhaps you can answer a question for me: The abiliity to use
multiple dots; are multiple dots allowed in IPV 4 ? Or are they an IPV 6
implementation? I though I had the papers on it but can't find them &
Google's no help so far.

Aren't you conflating some things here? IPV6 and IPV4 are merely
Internet addressing standards, IPV6 makes provision for the :: notation
to shorten the IP address. Dotted names like blah.com are URLs or domain
names and are resolved using other protocols such as DNS, etc.
