Iterating through a PHP array in jQuery?

How do I iterate through a PHP array in jQuery? I have an array in php named

$viewfields
.
How do I iterate through each element of this array using jQuery?

EDIT 1

<?php foreach ($viewfields as $view): ?>

if(<?=$view['Attribute']['type'];?>=='text'||<?=$view['Attribute']['type'];?>=='number')
{
$("<input id=input<?=$view['Attribute']['sequence_no'];?> type= 'text' style= 'width:<?=$view['Attribute']['size'];?>px' data-attr=<?=$view['Attribute']['type'];?> ></input><br>").appendTo("#fb_contentarea_col1down21 #<?=$view['Attribute']['sequence_no'];?>");
}


If i give

$.each(arrayfromPHP,function(i,elem){

}


how do I write the code for $view['Attribute']['type'] in jQuery?
elem['Attribute']['type'] won't work I suppose?

EDIT 2

elem['Attribute']['type'] does work

Answer Source
var arrayFromPHP = <?php echo json_encode($viewFields) ?>;

$.each(arrayFromPHP, function (i, elem) {
    // do your stuff
});

To better understand how the things are wired together (thanks Jonathan Sampson):

<!DOCTYPE html>

<html>
<head>
<script type="text/javascript">
var arrayFromPHP = <?php echo json_encode($viewFields) ?>;

$.each(arrayFromPHP, function (i, elem) {
    // do your stuff
});
</script>
</head>
<body>

</body>
</html>

You can of course place that SCRIPT tag wherever you want in the page, or you can even reference arrayFromPHP from external scripts as arrayFromPHP is declared as global.

EDIT

Given this PHP array:

$viewFields = array(
    'Attributes' => array(
        'type'  => 'foo',
        'label' => 'bar',
    ),
    'Attributes' => array(
        'type'  => 'foo',
        'label' => 'bar',
    ),
);

Accessing its elements with jQuery would be done like this:

// json_encode() will output:
// {"Attributes":{"type":"foo","label":"bar"}}

$.each(arrayFromPHP, function (i, elem) {
    alert(elem.type);
    alert(elem.label);
});
