[RESOLVED] Why on Earth isn't this working?

Hey all,

 I'm fairly new to PHP and could use some help.  If you look at the code, theoretically if you check the three checkboxes and then submit it should echo "a,b,c" but it doesn't echo anything.  If you uncomment the commented code, though, that code works just fine.  Why is this?

<html>
<body>
<form name="test" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<input type="checkbox" value="a" name="test[]">
<input type="checkbox" value="b" name="test[]">
<input type="checkbox" value="c" name="test[]">
<input type="submit">
</form>

<?php
$imploded = implode(",", (array)$_POST['$test']);
echo $imploded;//value,value,value if all are checked

/*
$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

echo $comma_separated; // lastname,email,phone
*/

?>
</body>
</html>

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
a. <input type="checkbox" name="test[]" value="a"><br>
b. <input type="checkbox" name="test[]" value="b"><br>
c. <input type="checkbox" name="test[]" value="c"><br>
<input type="submit" name="submit" value="submit">
</form>
<br>
<br>

<?php
if (isset($_POST['submit']))
{
	if (isset($_POST['test']))
	{
		echo 'you checked: ' . implode(', ', $_POST['test']);
	}
	else
	{
		echo 'you did not check anything';
	}
}
?>

maybe something like this?

<?php
if (isset($_POST['submit']))
{
$imploded = implode(",", (array)$_POST['$test']);
echo $imploded;//value,value,value if all are checked
$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone
}
else
{
echo '
<form name="test" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<input type="checkbox" value="a" name="test[]">
<input type="checkbox" value="b" name="test[]">
<input type="checkbox" value="c" name="test[]">
<input type="submit">
</form>';
}
?>

Thanks for the quick replies - I really appreciate it. Maybe it would have helped if I used the right variables...boy do I feel foolish!

Thanks
