You would typically convert the array to a JSON string with JSON.stringify, then make an AJAX request to the server, receive the string parameter and json_decode it to get back an array in the PHP side.

here is the (very) basic idea.

javascript

var arr=your array;
var str;
for(var i=0; i<arr.length; i++) {

    str+='&array_items[]='+arr[i];
}
document.location.href='url.php?'+str;

php

for ($i=0; $i<count($_GET['array_items']); $i++){ 

    $arr[] = $_GET['array_items'][$i];

}

//display php array on page
print_r($arr);

AJAX it. Just like anything else you want to send to the server without a full page reload.

You could convert the javascript to a PHP object too...

/**
* Takes a json encoded string and turns it into a PHP object
* 
* @param string string
* @return object
*/
public static function jsonToPhp($string)
{
    $obj = json_decode(stripslashes($string));
    if (!is_object($obj))
    {
        $obj = json_decode($string);
        if (!is_object($obj))
        {
            print "Cannot convert $string to an object";
                            return NULL;
        }
    }
    return $obj;
}

Requires that your javascript be converted to json.
