[Solved] First element of a foreach loop

[eluser]laegnur[/eluser]
Hi.

I'm new to CodeIgniter.

In a view I have the next code

Code:

<?php
  foreach ($a as $b)
  {
?>
<?php
    echo '<div>'.$b->field1.'-'.$b->field2.'</div>'."\n";
?&gt;
&lt;?php
  }
?&gt;

How can I identified the first "foreach" element, to apply a special css class to it.


Sorry for my bad english...

Edit: Thanks pistolPete and tomcode for your answers.

How about this:

Code:

$first = TRUE;
foreach ($a as $b)
{
    if($first)
    {
        echo '<div id="first">'.$b->field1.'-'.$b->field2.'</div>'."\n";
        $first = FALSE;
    }
    else
    {    
        echo '<div>'.$b->field1.'-'.$b->field2.'</div>'."\n";
    }
}

Even shorter :

Code:

$first = ' id="first"';
foreach ($a as $b)
{
    echo '<div' .$first .'>'.$b->field1.'-'.$b->field2.'</div>'."\n";

    if($first != '') $first = '';
}
