foreach alternate like table

You need to keep a counter, and check if that counter is even or odd. You can do this with modular division.

Code:

$count = 0;
foreach($list as $item) {
    if($count % 2) {
        $class = 'a';
    } else {
        $class = 'b';
    }

    echo '<div class="'.$class.'">code</div>';

    $count++;
}

You can shorten this with the ternary operator:

Code:

$count = 0;
foreach($list as $item) {
    echo '<div class="'.($count++%2?'a':'b').'">code</div>';
}

You can also use the alternator() function in the string helper: http://ellislab.com/codeigniter/user-gui...elper.html

Code:

for ($i = 0; $i < 10; $i++)
{
    echo alternator('string one', 'string two');
}
