Odd and Even numbers

Hallo,
I want to create a Perl script that will read a few lines from a database and then it will create an HTML table. The problem:
I need a function that will finds if a number is odd or even because I want to have defferent color to each line. Does anybody knows how to do that?

Use modula(%)-operator. If x%2 is 1 then odd . If x%2 is 0 then even. In Perl:

if ($number%2==1) {
# $number is odd
}
else {
# $number is even
}

------------------
Good luck,
Bas

I think you could do this in PERL, but this is PHP, i think it's a little cleaner than using an if-then construct.

$rowColors=Array("#cccccc","#eeeeee");
/*
I think the PERL would be something like:
@rowColor=("#cccccc","#eeeeee");
and then you use "print" and not echo,
right?
*/
$index=0;
echo "<table>";
for ($i=0;$i<10;$i++)
{
echo "<tr bgcolor=".$rowColors[$index]."><td></td></tr>";
$index=-($index)+1; // this makes it alternate
}
echo "</table>";

Hope that helps.

Hi again.
THe second message looked more like perl (or C++ ). I tries both solutions. I was thinking that the % was PHP too, but it worked fine.
So, I have to say thanks.
Cheers,
