the very first time it counts I want it to stop counting by 3 but then start counting by 2 but after that 2 start counting by 3 again etc...
I know this is possible in javascript but I don't want to go through the proccess of setting up the javascript to do this

I'd use an array. This is in C, but you should be able to do it easily in PHP:
int incr[2] = {2,3};
int cnt = 0;
for (int i = 1; i < 238; i+= incr[cnt]) {
cout << i << endl;
cnt++;
cnt %= 2;
}

<?php
$incr = array("2","3");
$cnt = 0;
for ($i = 0; $i <= 255; $i+= $incr[$cnt]) {
echo '<div style="background-color: rgb('.$i.','.$i.','.$i.');"></div>';
$cnt++;
$cnt %= 2;
}
?>

<br />
To White

Black<br /><br />
<?php
for($i = 0;$i <= 255;$i++){
echo '<div style="background-color: rgb('.$i.',0,0);"></div>';

Usually when you want to use a number you use numbers and not strings.
$x = "1" ;
$y = 1;
if($x === $y) {
echo "They're equal and of the same type.";
} else {
echo "They're either not equal or not of the same type.";
}
