fwrite in another fwrite?

[benq]

hi all

at the momeny i have this statement, which writes:

if (isset($_SESSION['checkbox10'])) {
fwrite($handle,'<td><xsl:value-of select="fgeu_code"/></td>'."\n");
}

this writes:

<td><xsl:value-of select="county_UA"/></td>

i want be able to add back colour to the td and i have this so far which writes the statement:

if (isset($_SESSION['radiobutton1']))
{
  if ($_SESSION['radiobutton1'] == 'chocolate')
     $colour = "#D2691E";
   elseif ($_SESSION['radiobutton1'] == 'forestgreen')
     $colour = "#228B22";
   elseif ($_SESSION['radiobutton1'] == 'turquoise')
      $colour = "#00DED1";
}
if (isset($_SESSION['checkbox11']))
 fwrite($handle,"<td bgcolor=\"$colour\"><xsl:value-of select=\"county_UA\"/></td>"."\n");

this writes:

<td bgcolor="#D2691E"><xsl:value-of select="county_UA"/></td>

i want to be able just to modify the exisiting line above but with out writing the entire code so it will only add the

bgcolor="#D2691E

so it will look like something like this i think:

fwrite($handle,<td bgcolor= fwrite($handle,\"$colour\"><xsl:value-of select=\"county_UA\"/></td>"."\n");

so it will write the line and if the colour is requested it will add the bkgriund colour.

is that possible?

thanks all

Like this?

$color_codes = array('chocolate' => '#D2691E', 'forestgreen' => '#228B22', 'turquoise' => '#00DED1');
$str = '<td';
if (isset($_SESSION['radiobutton1'])) { 
    $str .= ' bgcolor="' . $color_codes[$_SESSION['radiobutton1']] . '"';
}
$str .= '><xsl:value-of select="county_UA"/></td>' . "\n";

if (isset($_SESSION['checkbox11'])) { 
    fwrite($handle, $str);
}
