How to implode foreach() with comma?

foreach($names as $name) {
    //do something
    echo '<a href="' . $url . '" title="' . $title . '">' . $name .'</a>';
}

Want to add comma after each link, except the last one.

Answer 1

Raveren’s solution is efficient and beautiful, but here is another solution too (which can be useful in similar scenarios):

$elements = array();
foreach($names as $name) {
    //do something
    $elements[] = '<a href="' . $url . '" title="' . $title . '">' . $name .'</a>';
}
echo implode(',', $elements);
