原字符串1,2,3,4,5,6,
去掉最后一个字符","，最终结果为1,2,3,4,5,6
代码如下：
$str = "1,2,3,4,5,6,";
$newstr = substr($str,0,strlen($str)-1);
echo $newstr;
//echo 1,2,3,4,5,6
系统自带的函数即可实现这样的效果，两种方法：
substr($str, 0, -1)
//函数2
rtrim($str, ",")

其实说微信官方说的很简单，当你前端发送code到后台然后调用腾讯的api再返回session_key和openid时，不要直接返回到客户端（小程序）。而是让你自己生成一个随机数作为键，session_key+openid作为值，通过php自己设置一个session，然后保存到memache或redis。
$key = $this->session_3rd(128);
