关于php中利用sql语句创建表的问题

PHP code

求大神找找问题,一直报错 create error的问题..但是将sql语句复制出来之后,在phpmyadmin中,又可以完美创建,这是什么原因造成的?下面还有一个类似的情况.就是插入有问题..

------解决方案--------------------
$do=mysql_query($sql,$con) or die(mysql_error()); //改成这样看报错了没有，下面也是如此
------解决方案--------------------
第一段代码，经测试没有问题，表能正确创建
第二段代码中sql指令有误
$sql="insert into user2(name,password,age,sex,mail,qq,degree,fav)value('$user','$pass','$age','$sex','$mail','$qq','$degree','$fav_z')";
即 $qq 前少了个单引号
