how to create dynamic menu with sub-menu with php & mysql

Question

I want to have a dynamic menu that feeds from a table using php and mysql.

My table looks like this:

sec_id  sec_name    sec_group
1   section 1   g         


        

Answer 1

$q = mysql_query("SELECT sec_id, sec_name, sec_group FROM tbl_user_sec ORDER BY sec_id");

// prepare data 
$groups = Array();
while($w = mysql_fetch_assoc($q)) {
  if(!isset($groups[$w['sec_group']])) $groups[$w['sec_group']] = Array();
  $groups[$w['sec_group']][] = $w;
}

// display data
echo "
";
foreach($groups as $group_name => $sections) {
  echo '
'.$group_name.'
';
  foreach($sections as $section) {
    echo '
'.$section['sec_name'].'';
  }
  echo '
';
}
echo "
";

There is another solution if you don't care about sorting result by sec_id
