[SOLVED] For loops with increment other than one

hi there,

 

im creating a simple for loop statement with a simple form to go along with it.

here is my script:

<?php
print<<<HTML
<html>
<head>
<title>Activity Two- inc to start and stop counting as well increment to increase by</title>
</head>
<body>
<form method="post">
<input type = "text" name = "startint" value="start integer"><br>
<input type = "text" name = "stopint" value="stop integer"><br>
<input type = "text" name = "incr" value="increment to increase by"><br>
<input type = "submit">
</form>
HTML;
if (isset($_POST['startint']) && isset($_POST['stopint'])  && isset($_POST['incr']))
{
$startint = $_POST['startint'];
$stopint = $_POST['stopint'];
$incr = $_POST['incr'];
#this didnt work either settype($incr,"integer");
for($i = &$startint; $i <= $stopint; $i + $incr)
{
	print "<br>". $i;
}
}
?>

the issue is that it just echos the number 10 repeatedly. why is it that if i set the increment to $i ++ it works but not when i set the increment to anything other than one?

any help would be greatly apprecaited

thanks.
