从动态删除数组中的元素(Removing elements from array dynamically)

 所以我学会了如何动态地向数组添加元素 - 如何删除它们？ 
 
 jQuery的 
 
$(document).on('change blur', '.roomFac', function () {
        var park = $("#park2").val();
        var lecturestyle = $("#lecture_style2").val();
        var roomstructure = $("#room_structure2").val();
        var groupsize = $("#groupSize2").val();
        var facilities = "";
        $('select[name*=roomFac]').each(function () {
            facilities += $(this).val();
            facilities += ",";
        });
        var dataString = 'park=' + park + '&' + 'lecturestyle=' + lecturestyle + '&' +
            'roomstructure=' + roomstructure + '&' + 'groupsize=' + groupsize + '&' +
            'facilities=' + facilities;
        $.ajax({
            type: "POST",
            url: "process_timetableMon2.php",
            data: dataString,
            cache: false,
            success: function (html) {
                $('#mon').html(html);
            }
        });
    });
 
 process_timetableMon2.php 
 
$array = explode(",", $_POST["facilities"]);

for($i = 0; $i < count($array)-2; $i++){
    echo $array[$i].'<br>';
}
 
 我在这里上传了一些代码： http ： //jsfiddle.net/kfm5b/3/ 

So I've learnt how to add elements to an array dynamically - how about removing them?
 
jQuery
 
$(document).on('change blur', '.roomFac', function () {
        var park = $("#park2").val();
        var lecturestyle = $("#lecture_style2").val();
        var roomstructure = $("#room_structure2").val();
        var groupsize = $("#groupSize2").val();
        var facilities = "";
        $('select[name*=roomFac]').each(function () {
            facilities += $(this).val();
            facilities += ",";
        });
        var dataString = 'park=' + park + '&' + 'lecturestyle=' + lecturestyle + '&' +
            'roomstructure=' + roomstructure + '&' + 'groupsize=' + groupsize + '&' +
            'facilities=' + facilities;
        $.ajax({
            type: "POST",
            url: "process_timetableMon2.php",
            data: dataString,
            cache: false,
            success: function (html) {
                $('#mon').html(html);
            }
        });
    });
 
process_timetableMon2.php
 
$array = explode(",", $_POST["facilities"]);

for($i = 0; $i < count($array)-2; $i++){
    echo $array[$i].'<br>';
}
