如何防止在逗号结尾处插入逗号title3？

foreach ($_POST['titles'] AS $title) {
    echo "{$title},";
}; 

结果:

title1,title2,title3,

更新:它是一个表单数据,这是数组.不要这样来;title1,title2,title3,

<form>
<select name="titles[]">
<option>title1</title>
<option>title2</title>
<option>title3</title>
<option>title4</title>
</select>
</form>
