You can't loop like that, you need to loop the PHP array and push into javascript array:

<script type="text/javascript" language="javascript">
    var pausecontent = new Array();
    <?php foreach($schd_arr as $key => $val){ ?>
        pausecontent.push('<?php echo $val; ?>');
    <?php } ?>
</script>

There you go, complete solution:

<?php

$myarray = array(45,3,56,7,21);

//create a copy and sort
$myarray_copy = $myarray;
sort($myarray_copy);

//reverses key and values
$myarray_copy = array_flip($myarray_copy);

//create result by using keys from sorted values + 1
foreach($myarray as $val)
    $myarray2[] = $myarray_copy[$val]+1;

//print final array
print_r($myarray2);

/*
Output:

Array ( [0] => 4 [1] => 1 [2] => 5 [3] => 2 [4] => 3 )
*/
?>

The line:

var dataToSend = {'name' : val, 'ans[]' : <?php echo $answers; ?> } ;

will print:

var dataToSend = {'name' : val, 'ans[]' : Array } ;

which creates a ~~javascript syntax~~ semantic error (ans = empty string will be posted). Change to:

var dataToSend = {'name' : val, 'ans[]' : <?php echo json_encode($answers); ?> } ;

which prints:

var dataToSend = {'name' : val, 'ans[]' : [13,5,6,11] } ;

If you don't want to use javascript, you can handle it via php. Take a look at this lib: http://code.google.com/p/php-mobile-detect/. And then you could do something like:

<?php
include 'Mobile_Detect.php';
$detect = new Mobile_Detect();

if ($detect->isMobile()) {
    header('Location: yourpage.php');
    exit(0);
}

Cookies are not the way to transfer variables between client and server. you should append key/variables pairs to your request URL using either a get (querystring) or post method.

jQuery ajax example;

$.get('http://www.myphpserver.com/script.php?row_id=' + NewCookieValue);
