输出：string(1) "3" string(1) "3" 等于
方法：
public function view(){
$uid=I('uid');
$userid_coming=session('uid');
var_dump($uid);
var_dump($userid_coming);
if($uid!=$userid_coming){//当不是查看自已的资料时，记录来访--
$data=array(
'userid'=>$uid,
'userid_coming'=>$userid_coming,
'time_coming'=>mktime()
);
M('coming')->data($data)->add();
}else{
echo '等于';
}
$this->display();
}
插入数据库中的数据：
问题：
为啥var_dump输出的两个参数相等，但是却往数据库里插入了记录，而且insert到数据库的的userid也不是3，而是0;每次刷新页面都是这个结果；
而且开启调试模试时，所有的sql语句里看不到insert；不知道是何原因分别执行了if及else间的代码各一次，求解
