Its too early in the morning and i didnt click on any of the links - but
above might be the sort of thing your looking for rather than strpos() .

I had done that, and it is. In fact, if you look at

http://www.g8wrb.org/triodes/
http://www.g8wrb.org/triodes/index.phps

you will see it in the top right.

Sorry, you have lost me there.

I'll check that out.

Thanks a lot for that.

I implemented something based on what you suggested. I decided to move
ALL .php files (with the exception of the menu itself and the main home
page) to subdirectories.

i.e what was previously

http://www.g8wrb.org/y799.php
is now
http://www.g8wrb.org/y799/index.php

This means people will not have .php on the end of any links. Hence I
need to append index.php to my links before comparing with
$_SERVER['PHP_SELF']. But the following seems to be ok.




$links=array(
"Mathematica"=>"/mathematica/",
"Triodes"=>"/triodes/",
"Tetrodes"=>"/tetrodes/",
"Pentodes"=>"/pentodes/",
"Bases"=>"/bases/",
"Goodies"=>"/useful-stuff/",
"Application notes"=>"/application-notes/",
"Browse"=>"/data/",
"Thanks to"=>"/thanks/",
"Goodies"=>"/useful-stuff/",
"Solaris laptop"=>"/useful-stuff/Sun/laptop/",
"Y799"=>"/y799/",
"YC156"=>"/yc156/",
"New data"=>"/recently-added/",
"Yagi Uda"=>"/yagi/",
"Help"=>"/help/",
"Links"=>"/links/"
);

foreach($links as $key=>$value){
// compare the actual file name with the data above, after
appending index.php"
$fullfile=$value."index.php";
$f=$_SERVER['PHP_SELF'] ;
// echo "$f $fullfile<br><br>";
if( $_SERVER['PHP_SELF'] !=$fullfile)
echo "<li><a href=\"$value\">$key</a></li>\n";
}


I might look some time at creating some sub-menus. Even if my menus are
not the best in the world, I'd rather something I understand, than some
black-magic which works.
