How to add a <br/> after each result, but not last result?

Question

This is my partial code:

while($row = $db->fetch_array($query))
{
     echo $row['row_name'];
}

How can I make it so it will add a break tag after each result, but not the last result?

Answer 1

Put the output into an array, then join the array with implode:

$rows = array();
while($row = $db->fetch_array($query))
{
     $rows[] = $row['row_name'];
}
echo implode('<br/>', $rows);
