Question

i hoping to create a recursive function which i don\'t have an idea yet

this is my code to fetch category from database

Answer 1

Something like this?

function getCategories($mid, $categoryParent = 1)
{
    $return = '';
    $results = mysql_query("SELECT * FROM categories WHERE category_parent = '$categoryParent' ORDER BY lft ASC", $mid);
    while($row = mysql_fetch_array($results)) {
        $return .= "
{$row['category_name']}
";
        $subs = getCategories($mid, $row['category_id']);
        if (!empty($subs)) {
            $return .= '
';
            $return .= $subs;
            $return .= '
';
        }
    }
    return $return;
}

$mid = mysql_connect($host, $user, $pass);
echo getCategories($mid);

Would print out all your categories, of course fix it to exactly how you want, but that should give you an idea of how recursive functions could work
