echo MySql column names and values

Question

What I need is to have a list name => value to be able to make MySql queries. My problem is, I can access MySql records, but I also need to access table's column names, what should I change in my code?

Thanks

$query = "SELECT * FROM test_table";
$result = mysql_query($query) or die("Erro!: " . mysql_error());
if (mysql_num_rows($result) > 0) {
    $row = mysql_fetch_array($result);
    if(is_array($row)) {
        foreach ($row as $col => $val) {
            echo $col." = ".$val."<br>";
        }
    }
}

ok, so now why can't I join the values to then make my sql queries?

while($row = mysql_fetch_assoc($result)) {
        foreach ($row as $col => $val) {
            $colunas .= join(",",$col);
            $valores .= join(",",$val);
        }
        echo "colunas = ".$col."<br>";
        echo "valores = ".$val."<br>";
    }

I just get empty colunas and valores

Thanks, sorry if it seems to easy, but I'm lost

You needs while loop and a call to mysql_fetch_assoc

  while($row = mysql_fetch_assoc($result)) {   
        foreach ($row as $col => $val) {
            echo $col." = ".$val."<br>";
        }
    }
