Send JSON array alongside HTML form

[russthebarber]

I have a basic form as follows:

<form action="myForm_submit.php" method="post" accept-charset="utf-8" name="myForm">
<input type = "text" name="firstName" />	
<input type = "text" name="lastName" />	

<input type="submit" value="Submit">
</form>

And I have a javascript array:

myArray = ["bananas", "apples", "pears", "peaches", "oranges"];

When I hit submit and send my form data I would like to send myArray in JSON format to my php submit file. How would I do that and how would I code the php $_POST = ..... for my JSON array?

<?PHP
echo $_REQUEST["aray"];
?>

<form method="post" accept-charset="utf-8" name="myForm" onsubmit="addJSON(aray)">
<input type = "text" name="firstName" />	
<input type = "text" name="lastName" />	
<input type = "hidden" name="aray" >
<input type="submit" value="Submit">
</form>

<script>
myArray = ["bananas", "apples", "pears", "peaches", "oranges"];
function addJSON(el){
	el.value=JSON.stringify(myArray)
}
</script>

Thanks for the reply.

myArray = ["bananas", "apples", "pears", "peaches", "oranges"];

is just an example to simplify what I am trying to do. I actually have a large form with hundreds of fields to send. That's why I wanted to do it with one JSON array and not with hundreds of hidden input fields.

so uh well these fields ?
are not form elements ?
that the user types in ?
where do they come from ?

No, they are not form elements. They come from two large javascript arrays. I need to send all this data with the form. The form alone has about 100 elements at the moment and the arrays both have about 150 elements.
