怎么把powerdesigner导出的sql用PHP导入MysQL数据库

我们知道用powerdesigner导出的sql文件后缀为'.sql'；用phpmyadmin很容易导入MysQL数据库，但是用PHP怎么导入数据库呢?

我用powerdesigner设计一个数据库后导出sql文件（一个投票系统）为'vote.sql'；

文件内容为（一些sql语句和注释）：

alter table account_charge add constraint FK_Relationship_8 foreign key (chargewayid)

alter table account_cost add constraint FK_Relationship_4 foreign key (accountid)

alter table vote_item add constraint FK_Relationship_6 foreign key (votetitleid)

references vote_title (votetitleid) on delete restrict on update restrict;

此时我把整个语句当成一个sql语句用PHP的mysql_query来执行，结果错误。经过查阅一些资料得到
mysql_query每次只能执行一条语句！

于是用下面的循环执行即可：

$file='vote.sql';

$fh=fopen($file,'rt');

$data=fread($fh,filesize($file));//读取文件中的全部内容

$sqlarray=explode(';',$data);//每条sql语句由';'隔开

foreach($sqlarray as $sqlvalue)

{

mysql_query($sqlvalue);

}

此时PHP能顺利执行！
