Alternating table rows

[BlodoPKNZ]

I just cant seem to figure this one out. Im trying to get mysql results to show up in a table with alternating rows. My code:

PHP Code:

function rowbg() {
static $j=1;
if ($j%2 != 0.5) {
echo "display_row1";
$j++;
} else {
echo "display_row2";
$j++; }
} 


then i do:

PHP Code:

<tr class="<?php rowbg(); ?>">

to make it alternating. However it just returns the first case. Now where is my error?

1 % 2 = 1
2 % 2 = 0
3 % 2 = 1
4 % 2 = 0
5 % 2 = 1
