PHP email form help

[C__Casey]

Hi I've got a email form that uses array and a switch call to send values in a form to my email. The problem I'm having is I have a checkbox where users should be able to select multiple values however if they do when I receive the email instead of having the values it prints "ARRAY"...I've included a sample below:

<?
// Key => (required, type, string)

// Types:
// 1 - Long text
// 2 - Short text
// 3 - Textarea
// 4 - Radio
// 5 - Checkbox
// 6 - Dropdown

// 4, 5, and 6 require a 4th value in the array

$mail_form_to = "[e-mail]";
$mail_form_subject = "Real Estate Submission";

$values = array(
"present"				=> array(1, 5, "If land property, please indicate which of the following are present:", 
						array("Access to land via road","road","water"))
);

if ($_POST["submitform"] != "") {
	$errors = array();
	$areerrors = 0;
	foreach($values as $key => $value) {
		if ($value[0] == 1 && $$key == "") {
			$errors[$key] = 1;
			$areerrors = 1;
		}
	}

if (!$areerrors) {
	$count = 0;
	foreach($values as $key => $value) {
		$$key = stripslashes($$key);
		$count++;
		$email_body .= $count . ") " . $value[2] . "\n";
		$email_body .= "- " . $$key . "\n\n";
	}
	mail($mail_form_to, $mail_form_subject, $email_body, "From: Test <[e-mail]>");		header("Location: good.php");
	exit();
} else {
	foreach($_POST as $key => $value) {
		if (!is_numeric($key)) $$key = htmlentities(stripslashes($value));
	}
}
} 
?>

///switch statment below

<?
					  $count = 0;
					  foreach($values as $key => $value) {
					  	$count++;
					  	?>
                              <p align="left">
                                <? if ($errors[$key] == 1) echo "<font color=red>";?>
                                <?=$count?>
                                .
                                <?=$value[2]?>
                                <? if ($value[0] == 1) echo "*"; ?>
                                <? if ($errors[$key] == 1) echo "</font>";?>
                                <br />
                                <?
					  	switch ($value[1]) {

						case "5": foreach($value[3] as $key2 => $value2) { 
									echo "<input name=\"$key"."[]\" type=\"checkbox\" value=\"".htmlentities($value2)."\"";
									if (is_array($$key) && in_array($value2, $$key)) echo " CHECKED";
									echo "> $value2 ".$$key."<br>"; 
								  } break;
						default: echo "OTHER ITEM TYPE: $value[2]"; break;
					}
					?>

Any suggestions on having the checkbox submit the individual values accordingly instead of outputting "Array"?

since the checkbox is an array itself
<input name=\"$key"."[]\"
it makes post a partial 2d array.
$POST['key'][0]
$POST['key'][1]
etc.

so you may need to do

foreach($_POST['key'] as $key => $value) {
 ...
}
