<br> every 4th result from sql - php

Question

Simple question of course But I still could not figure it till now :) Im pulling names out of an sql and I want to be like 1 2 3 4,then next Line like 5, 6, 7, 8 Like So
<a>Bob</a>, <a>John</a>, <a>Bob</a>, <a>John</a> <BR>
<a>Bob</a>, <a>Ion</a>, <a>Bob</a>, <a>Pon</a> <BR>
Well thats What I want it To look like But For Now Its One Row Endless with no spaces is what I acheved so far Like So :)
<?PHP
require('connect.php');
$sql="SELECT * FROM profile";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result)){
$name =$row['username'];
$power =$row['power'];
?>
<span class='user-group-<?PHP echo $power; ?>'><?PHP echo $name; ?></span> ,
<?PHP } ?>
Now What Do I need to do to have every forth result + that space :?

Answer 1

Use an $i counter:
require('connect.php');
$sql = "select * from profile";
$result = mysql_query($sql);
// Start at 1
$i = 1;
while($row = mysql_fetch_array($result)){
$name = $row['username'];
$power = $row['power']; ?>
<span class='user-group-<?php echo $power; ?>'><?PHP echo $name; ?></span>
<?php
// When hit 4, add <br />
if($i == 4) {
echo '<br />';
// Reset to 0. $i will then auto-increment
// to 1 when hits $i++
$i = 0;
}
else
// Add comma if not equal to 4.
echo ',';
$i++;
}
