Topic awaiting preservation: quick php question (Page 1 of 1)

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

$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
