hello
i got a database and i am reading some links out of it in divs
however, i want that every second div gets another background-color than the first one (by using the echo tag and defining css classes)
so it goes like this
class1
class2
class1
class2
class1
......
help would be very appreciated

code:
$tmp = 0;
$class = array('class1', 'class2');

while (reading database content)
{
print "<div.... class=\"".$class[$tmp]."\"...></div">;

$tmp = ($tmp++) % 2;

}



That should work. What it does is increase $tmp each loop, but when $tmp equals 2 it is set to 0. That way the $tmp variable will alternate between 0 and 1. If you want to add more classes just add the class name to the $class variable and change the 2 to the number of classes you're using.

That is a great answer. I think I will have to use this somewhere. I just wouldn't have thought of the mod #classes.

If you use an array to store the class IDs, you'd rather go for :

$tmp = ($tmp+1) % count( $class );

If you use only 2 different class IDs, you can do:

$tmp = ++$tmp & 1;

or my favorite

$tmp ^= 1;

thx for the solution guys
veneficuz: BIG THX...the only thing is that $tmp = ($tmp++) % 2; didn't work for me but $tmp = ($tmp+1) % count( $linkreaddiv ); did
thx again
