php loop help

Here's my code:

echo "<select name=fromday>";
echo "<option value=0 selected>--Day--</option>";
$i = 1;
while ($i <=31)
{
echo "<option value=$i> $i</option>";
$i++;
}

echo "</select>";

How can I change this that for numbers 1-9 it should put 01,02,03 etc and not 1,2,3

echo "<select name=fromday>"; 
echo "<option value=0 selected>--Day--</option>"; 
$i = 1; 
while ($i <=31) 
{ 
  if($i < 10) {
    echo "<option value=\"0".$i."\">0".$i."</option>"; 
  } else {
    echo "<option value=\"".$i."\">".$i."</option>"; 
  }
$i++; 
} 
echo "</select>"; 

I think that should do the trick,

Thanks.

Easy solution but somehow I didn't think of it.

You could also use printf(), as this is an instance where it comes handy:

<?php
echo "<select name=\"fromday\">\n"
	. "<option value=\"0\" selected>--Day--</option>\n";
for ($i = 1; $i < 32; $i++) {
	printf("<option value=\"%'02d\">%'02d</option>\n", $i, $i);
}
echo "</select>";
?>
