How to display serial numbers in foreach loop while querying posts?

Question

Ok, I have a custom post type to store list of urls. I would like to print those urls with serial numbers. I used foreach loop.

foreach($urls as $url){
echo $url;   

I got n number of urls as output. But i want to print serial numbers in each url like 1,2,3 and so on. I don't want to use unordered list. Because i want to style my serial numbers too. So is there any way to print serial numbers?

Answer 1

How about:

echo '<ul>';

$sn_count = 1;
foreach($urls as $url){
    echo '<li><span class="serial-number">'.$sn_count.'</span> '.$url .'</li>';
    $sn_count++;
}

echo '</ul>';

You can then style your serial numbers with the serial-number class.
