Table look like using fopen

//connect to MySQL

$txt = 'output.txt';
$write = "id Name age color\n";

$handle = fopen($txt, 'atb');
fwrite($handle, $write);
fclose($handle);
 
//then i do the query to MySQL

while ($db_row=mysql_fetch_array($db_table)){
    extract($db_row);
    $write = $id . $name . $age . $color . "\n";
    $handle = fopen($txt, 'atb');
    fwrite($handle, $write); }

//a little stuff to make the headers fit a size, of curse you can resize the 'columns'      
$id = "id";
$id = str_pad($id, 5, " ");
$name = "Name";
$name = str_pad($name, 12, " ", STR_PAD_BOTH);
$age = "age";
$age = str_pad($age, 5, " ",STR_PAD_LEFT);
$color = "color";
$color = str_pad($color, 12, " ", STR_PAD_BOTH);  

$write = $id . $name . $age . $color . "\n";

//the next stays the same
$handle = fopen($txt, 'atb');
fwrite($handle, $write);
fclose($handle);

//then apply the same style to the content
//i made a little change on the name, you can do what you want
while ($db_row=mysql_fetch_array($db_table)){
        extract($db_row);
        $id = str_pad($id, 5, " ");
        $name = str_pad($name, 12, " ");
        $age = str_pad($age, 5, " ",STR_PAD_LEFT);
        $color = str_pad($color, 12, " ", STR_PAD_BOTH);  
        $somecontent = $id . $name . $age . $color . "\n";

//the rest is the same
