Tree Structure

[raj_2006]

Hi All,

I got this following tree structure code in this forum after searching.But I like to change the display.

I would like to display like this:

1
2 3
4 6
5 7

Code:

function recursive($results){
if(!is_resource($results)){
$sql = "SELECT * FROM `tab` WHERE `parent` = '".$results."' ORDER BY id;";
$results = mysql_query($sql);
}
$return = Array();
while(($row = mysql_fetch_assoc($results)) !== false){
$return[] = $row;
$sql = "SELECT * FROM `tab` WHERE `parent` = '".$row['id']."' ORDER BY id;";
$results2 = mysql_query($sql);
if(mysql_num_rows($results2) > 0){
$return[count($return)-1]['parent'] = recursive($results2);
}
}
return $return;
}



function tree($item, $key){
echo "<div style='float:left; margin:5px; '>".$item['id']."<br />\n";
array_walk(recursive($item['id']), 'tree');
echo "</div>\n";
}

$start = 1;
echo $start."<br />";
array_walk(recursive($start), 'tree');

Please suggest me how can i display like above

Thanks in advance.
