用phpexcel处理excel表然后导入bae数据库，死活不成功。：报错

都问了好几个人，都解决不了。求技术大牛帮忙解决下。代码如下：

<?php
header("content-type:text/html;charset=utf-8");
//$dbname = "ojRsUjRnxWVSelwkHAFu";
//百度bae数据库 这就是生成的数据库，要替换成自己的
      
/*从环境变量里取出数据库连接需要的参数*/  
/*function conn(){
//$conn01 = mysql_connect("sqld.duapp.com",'root','');//root是帐号,123456是密码
$conn01 = mysql_connect("sqld.duapp.com:4050",'37f01a0477c04fb8a4507839b4727f38','91f29eceab084d5dab60628af1cb948a');//root是帐号,123456是密码
$mycon=mysql_select_db('ojRsUjRnxWVSelwkHAFu',$conn01); //testdatabase是mysql数据库名
if($mycon){
echo("数据库连接成功");
}else{
echo("数据库连接失败");
}
}
conn();
echo 111;*/
