Change bgcolor based on value

[jeff5656]

This array echoes which_date <td>.  The values range from 1 to 31 and all in between.

How do I modify this to say: if the current value equals today's date (i.e. "1" if it's 12/1/08), then make the bgcolor red fo that <td>?

 

<table >";
$varArray = array("which_date");
$varArraySize = count($varArray);

for ($i = 0; $i < $varArraySize;$i++) {

   for ($f = 1; $f < 32; $f++) {
     echo "<td style='border-bottom-style: solid;'> " . $row[$varArray[$i] . $f] . "</td>";
 echo "<tr>";
   }
   

}
echo "</table>

<?php
$currentDay = intval(date('j')); //Current day
$days = intval(date('t')); //How many days has the current month

for ($iDay=1; $iDay <= $days; $iDay++)
{
   if ($iDay == $currentDay)
       echo '<b style="color:red;">'.$iDay.'</b>';
   else
       echo $iDay;
}
?>

Sorry I'm really bad with understanding arrays - how do I put your code into my own code?  My own code has variables like 1, 2, etc up to 31 but they are NOT recognized as dates of the month, inly absolute values.
