php - 将复选框值输入mysql

Question

我有以下复选框

<input type="checkbox" name="weekday[]" value="Monday" /> Monday &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="weekday[]" value="Tuesday" /> Tuesday &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="weekday[]" value="Wednesday" /> Wednesday </br>
<input type="checkbox" name="weekday[]" value="Thursday" /> Thursday &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="weekday[]" value="Friday" /> Friday &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="weekday[]" value="Saturday" /> Saturday &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="weekday[]" value="Sunday" /> Sunday &nbsp;&nbsp;&nbsp;

我想将所有选中的值输入到 mysql 中的“day”字段中，用逗号分隔，

请帮忙
