  有时写程序时后台要求把大量数据导入数据库中,比如计算机考试成绩的查询、电话簿的数据等一般都是存放在excel中的,这时我们可把数据导出成csv文件,然后通过以下程序即可在后台批量导入数据到数据库中。

  下面只是主要程序部分:

//定义获取时间函数
function getmicrotime(){
    list($usec, $sec) = explode(" ",microtime());
    return ((float)$usec + (float)$sec);
}
?>

$time_start = getmicrotime();
include("db.inc.php");//连接数据库
$db=new testcsv;
?>
$handle = fopen ("test.csv","r");
$sql="insert into scores(idcard,names,num,sex,nation,score) values('";
while ($data = fgetcsv ($handle, 1000, ",")) {
   $num = count ($data);
   for ($c=0; $c        if($c==$num-1){$sql=$sql.$data[$c]."')";break;}
       $sql=$sql.$data[$c]."','";
   }
print "
";
echo $sql."
";
$db->query($sql);
echo "SQL语句执行成功!
";
$sql="insert into scores(idcard,names,num,sex,nation,score) values('";
}
fclose ($handle);
$time_end = getmicrotime();
$time = $time_end - $time_start;
echo "程序执行时间:".$time."秒";
?>
