来自已使用“POST”方法提交。确定哪些复选框并按升序写下它们的编号。用空格（不是换行）分隔所有数字，并且不使用任何 HTML 格式。

例如：
If check-boxes 3, 5 and 10 are checked.
如果复选框 3、5 和 10 被选中。
Ouput would be:
输出将是：
3 5 10
3 5 10

Change the markup to something like
将标记更改为类似
<input type="checkbox" class='form' value="1" name="checkbox[]" />
<input type="checkbox" class='form' value="2" name="checkbox[]" />
<input type="checkbox" class='form' value="3" name="checkbox[]" />
and to get the values submitted, use a simple loop
并获取提交的值，使用一个简单的循环
foreach($_POST['checkbox'] as $checkbox){
echo $checkbox . ' ';
}

HTML Code ::
HTML 代码 ::
<input type="checkbox" name="arrayValue[]" value="value1" > value1 <br />
<input type="checkbox" name="arrayValue[]" value="value2" > value2 <br />
<input type="checkbox" name="arrayValue[]" value="value3" > value3 <br />
<input type="checkbox" name="arrayValue[]" value="value4" > value4 <br />
php code::
php代码::
$checkBoxValue = join(", ", $_POST['arrayValue']); // here first (,) is user-define
// means, you can change it whatever
// you want, even if it can be (space) or others
now you get the whole value of 'checkbox' in one variable
现在您可以在一个变量中获得“复选框”的全部值

Iterate over the $_POSTarray and use preg_match()to pull out the number if it starts with "checkbox_":
迭代$_POST数组并用于preg_match()提取以“checkbox_”开头的数字：
$checked = array();
foreach ($_POST as $k => $v) {
if (preg_match('|^checkbox_(\d+)$!', $k, $matches) {
$checked[] = $matches[1];
}
}
echo implode(' ', $matches);

<?php
$checked = array();
foreach ($_POST as $k => $v) {
$subject = $k;
$pattern = '/^checkbox_(\d+)$/';
if (preg_match($pattern, $subject, $matches))
{
$checked[] = $matches[1];
}
}
asort($checked);
foreach ($checked as $key=>$value)
echo $value .' ';
?>

For your Each Checkbox value retrieval you can use below method to get values from checkbox are checked or not....
对于您的每个复选框值检索，您可以使用以下方法从复选框中获取值是否被选中....
In My Form Page (Monday to Sunday)
在我的表单页面（周一至周日）
<input type="checkbox" name="checked[]" class="onoffswitch-checkbox" id="mononoffswitch" value="Mon" checked>
In My PHP Code
在我的 PHP 代码中
function IsChecked($chkname,$value)
{
if(!empty($_POST[$chkname]))
{
foreach($_POST[$chkname] as $chkval)
{
if($chkval == $value)
{
return true;
}
}
}
return false;
}
if(IsChecked('checked','Mon'))
{
$checkedMon = "Y";
}else {
$checkedMon = "N";
}
if(IsChecked('checked','Tue'))
{
$checkedTue = "Y";
}else {
$checkedTue = "N";
}
if(IsChecked('checked','Wed'))
{
$checkedWed = "Y";
}else {
$checkedWed = "N";
}
if(IsChecked('checked','Thur'))
{
$checkedThur = "Y";
}else {
$checkedThur = "N";
}
if(IsChecked('checked','Fri'))
{
$checkedFri = "Y";
}else {
$checkedFri = "N";
}
if(IsChecked('checked','Sat'))
{
$checkedSat = "Y";
}else {
$checkedSat = "N";
}
if(IsChecked('checked','Sun'))
{
$checkedSun = "Y";
}else {
$checkedSun = "N";
}
Now you can get these variable values and can use in to your Insert Into statement ...
现在您可以获得这些变量值并可以用于您的 Insert Into 语句......
Like this
像这样
$addweekdays = mysqli_query($conn, "INSERT INTO weekdays(id,monday,tuesday,wednesday,thursday,friday,saturday,sunday) VALUES('$Id', '$checkedMon', '$checkedTue', '$checkedWed', '$checkedThur','$checkedFri','$checkedSat','$checkedSun')") ...

take an array for name of your checkbox as name="checkbox[]"and use same name for all your checkbox.
After submitting your form receive the values of checked checkbox by using following code:
取一个数组作为复选框的名称，name="checkbox[]"并为所有复选框使用相同的名称。提交表单后，使用以下代码接收选中复选框的值：
<?php
$chk="";
foreach($_POST['checkbox'] as $checkbox)
{
$chk=$chk.$checkbox;
}
echo $chk;
?>
