有时写程序时后台要求把大量数据导入数据库中，比如考试成绩、电话簿等一般都是存放在excel中的数据，这时我们可把excel导出成csv文件，然后通过以下程序即可批量导入数据到数据库中
上传cvs并导入到数据库中，测试成功（部分代码不规范，如PHP_SELF那里要改写成
$_SERVER["PHP_SELF"] ）
PHP代码
<?php
$fname = $_FILES['MyFile']['name'];
$do = copy($_FILES['MyFile']['tmp_name'],$fname);
if ($do)
{
echo"导入数据成功
";
} else {
echo "";
}
?>
<form ENCTYPE="multipart/form-data" ACTION="<?php echo"".$PHP_SELF.""; ?>" METHOD="POST">
导入CVS数据 <input NAME="MyFile" TYPE="file"> <input VALUE="提交" TYPE="submit">
</form>
<?
error_reporting(0);
//导入CSV格式的文件
$connect=mysql_connect("localhost","a0530093319","123456") or die("could not connect to database");
mysql_select_db("a0530093319",$connect) or die (mysql_error());
$fname = $_FILES['MyFile']['name'];
$handle=fopen("$fname","r");
while($data=fgetcsv($handle,10000,","))
{
$q="insert into test (code,name,date) values ('$data[0]','$data[1]','$data[2]')";
mysql_query($q) or die (mysql_error());
}
fclose($handle);
?>
用php将数据库导出成excel，测试完全成功
PHP代码
<?php
$DB_Server = "localhost";
$DB_Username = "a0530093319";
$DB_Password = "123456";
$DB_DBName = "a0530093319";
$DB_TBLName = "member";
$savename = date("YmjHis");
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password)
or die("Couldn't connect.");
mysql_query("Set Names 'gb2312'");
$file_type = "vnd.ms-excel";
$file_ending = "xls";
header("Content-Type: application/$file_type");
header("Content-Disposition: attachment; filename=".$savename.".$file_ending");
header("Pragma: no-cache");
header("Expires: 0");
$now_date = date("Y-m-j H:i:s");
$title = "数据库名:$DB_DBName,数据表:$DB_TBLName,备份日期:$now_date";
$sql = "Select * from $DB_TBLName";
$ALT_Db = @mysql_select_db($DB_DBName, $Connect)
or di
