Work the statement from right to left.

Server variables: $_SERVER['PHP_SELF']
The filename of the currently executing script, relative to the document
root. For instance, $_SERVER['PHP_SELF'] in a script at the address
http://example.com/test.php/foo.bar would be /test.php/foo.bar.

explode('/',$_SERVER['PHP_SELF'])
explode Split a string by string returns an array of strings
returns array('temp','mydri','index.php')

array_pop(explode('/',$_SERVER['PHP_SELF']))
array_pop() pops and returns the last value of the array...
returns 'index.php'

explode('.',array_pop(explode('/',$_SERVER['PHP_SELF'])))
explode Split a string by string returns an array of strings
returns array('index','php')

array_shift(explode('.',array_pop(explode('/',$_SERVER['PHP_ SELF']))))
array_shift() shifts the first value of the array off and returns it...
returns 'index'

Er, N, it's all in the RTFM.

Start from the inside out...

$_SERVER['PHP_SELF'] contains the path of the current file, from the web
root IIRC, something like
/folder/folder/file.ext

_explode_ this into an array, delimited by /

folder,
folder,
file.ext

_array-pop_ the *last* element in the array

file.ext

explode this on .

file,
ext

_array_shift_ the *first* entry out of this array

file

On looking at the above (written the odd several years ago) I admit the
whole thing should now be shortened into a preg_match() or two. May do that
some day. Then again I now my create menus directly from the database and
the routines that access that database know *exactly* what "page" they are
in and they know *precicely* how to write the HTML that will, in due couse,
be selected by the appropriate CSS rules.

True. Just a different programmers coding expression of the "algorithm".

Okay, thanks, I pretty much get it now. The prob is I'm just not that
familiar with php in depth. Sure, it's great, but I only use it when I
convince myself I absolutely have to because it does produce a delay in
rendering a page. While this delay is quite small, typically about a
second or less, and is not particularly bothersome per se, the glaring
white blank background displayed by most browsers during the wait is.
Mozilla seems to be the only one of the major offerings that doesn't
suffer from this anomoly.

I think my troubles were that I just couldn't intuitively get a handle on
$_SERVER['PHP_SELF'] because the FM didn't give any usage examples (which
I could find), and I'd never even heard of "explode" before. Your
explanation clarifies it beautifully although excessive nesting still
makes me a little bird-brained. 'Tis, indeed, a clever sequence of
functions to derive the active client page filename.

I've used that in the past for browser-sniffing. Worked fine if one was
careful enough in setting the _whole_ thing up.

You must be doing something wrong.

Most of my pages are done with PHP, and I do not experience what you
describe, with any browser.

Okay, I checked Opera and found to my amazement that I didn't have the
default bg set (-or rather, it was set to white.) 'Could've swore I set
that, but it was several updates ago so the Opera company is probably the
one at fault...

That leaves ie6, which will be ie6. (Have ie7 on another box; will check
it later.)

There's still a delay, but with a dark bg, it's not too bad.

Sure, I even remember having to do that a long time ago back when I had a
printer (-all of which, afaik, need both line feeds and carriage returns to
"proceed",) but got used to the \n alone from scripting the java. PHP is a
relative newcomer but alike in many ways to j/s.

I don't think I'll answer that one...

Normally, white is a modern browser's default background color. Earlier
ones used grey, as I recall, old Netscapes, old IEs. In my most-used
browsers, I always set something different, so I can see when authors
forget to assign a background color. It makes for some interesting
viewing.

IE6 was white, as I recall.

If there is a delay that is truly caused by using PHP, you must be
coding something odd, or it is your web server's fault. Mine all have no
delay whatsoever, in any browser.

Good idea. I usually go for dark gray or black (with light monochromatic
text) - my preference.

Well, I've noticed delays (again - very small, from 0.5 to 2.0 secs appx.)
on _all_ my php creations, so I guess it's the server, which is Yahoo. A
second or so doesn't seem that bad to me as long as some glaring white
background isn't blinding you in the interim.
