On those rare occasions when it doesn't work, have you looked at the source
code to see what the output was? print_r($files) ; to see if . and .. are
included in the file list. If they are, those might be casusing your
problem. If not, see the output when it doesn't work and try to figure what
went wrong. Another guess would be non-ascii characters in filenames don't
translate to url, like characters with umlauts or stuff like that.

Occasionally you get . or .. in which case you won't see a picture. If
your files are all .jpgs, try $files = glob("./gfx/zufall/*.jpg");
Alternatively try (untested):
$files = glob("./gfx/zufall/*");
shuffle ($files);
foreach( $files as $key=>$value){
if ($value=="." || $value==".."){
unset($files[$key]);
}
}
echo "<a href='index.php '><img src='".$file[0]."' height='341'
width='634' border='0'></a>";
}

Ummm, that should be:-
$files = glob("./gfx/zufall/*");
shuffle ($files);
foreach( $files as $key=>$value){
if ($value=="." || $value==".."){
unset($files[$key]);
}
}

Close, Goeff. But I think you want to remove the pseudo-files before
you shuffle. What happens if after the shuffle one of them comes up as
element 0?
Just putting the shuffle() after the foreach loop should work better.

Hi,
When I do a select with a limit I get always the same records. Usually this

But now I want to do a random select. So every time I do a select I should

What is the best way to achieve this effect?

I need to generate 2 random numbers in rapid sequence from either PHP or

I have not been able to do either. I get the same number back several times

any ideas?
I suppose I could use the current rancom number as the seed for the next
random number. but would that really work?
