jquery - Loop through AJAX posted array of checkboxes with PHP -


i've spent quite bit of time looking how this. basically, have few checkboxes sending through ajax php script, , want php script echo value of each selected checkbox.

here code checkboxes:

while ($template = $stmt->fetch(pdo::fetch_assoc)){     echo("<input class='checkbox templateselectbox' name='relatedtemplates[]' data-template='". $template['id'] ."' value='".$template['id']."' type='checkbox'> <p class='label label-default'>". $template['name'] ."</p><br>"); }

with php code, there 3 checkboxes on page. here ajax sends checked checkboxes: 

$.ajax({    type: 'post',    url: 'inc/ajax/addserver.ajax.php',    data: {'selectedtemplates': $(".templateselectbox:checked").serialize()},    success: function(data){       $("#responses").html(data);    }  })

then if check second checkbox , echo using echo($_post['selectedtemplates']), echoes relatedtemplates%5b%5d=2, don't understand why. i'm expecting value of checkbox, single digit. instead i'm getting string.
