If it's just a simple flat array you don't need to do anything fancy, as PHP has a built in feature to parse array syntax from GET/POST variable names. Rough example below.

Javascript side:

// Do the parameter-building however you want, I picked the short/messy way
var arrayvalues = [1, 2, 'a'];
var querystring = "var[]=" + arrayvalues.join("&var[]=");
querystring += "&var[something]=abcdef";
// querystring is now "var[]=1&var[]=2&var[]=a&var[something]=abcdef"

PHP side:

var_dump($_POST);
// Remember to validate the data properly!
if ( is_array($_POST['var']) ) {
    count($_POST['var']);
    echo $_POST['var']['something'];
    array_map('do_something_interesting', $_POST['var']);
}
