Answer 1

On a side note; your javascript could be refactored into something a bit more simple

$("td").click(function() {
    $(this).toggleClass('selectedBox');

    // map text of tds to selectedValues
    var selectedValues = $.map($("td.selectedBox"), function(obj) {
            return $(obj).text();
    });

    // $.post('/url/to/page', {'someKeyName': variableName}); //exemple
    $.post('handler.php', 
          {'serializedValues' : JSON.stringify(serializedValues)}, 
          function(data) {
            //debug 
         }
    );
});

Answer 2

You should serialize your array into json string:

serializedValues = JSON.stringify(selectedValues)

And pass it to php. And then decode with json_decode:

$originalValues = json_decode($_POST['serializedValues'], 1);
