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<br>";;;
} else {;
echo "";;;
};
?>;
<form ENCTYPE="multipart/form-data" ACTION="<?php echo"".$PHP_SELF.""; ?>" METHOD="POST">;;
<p>导入CVS数据; <input NAME="MyFile" TYPE="file"> <input VALUE="提交" TYPE="submit">;;
</p>;
</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 www.devdao.com
<?php;
$DB_Server = "localhost";;
$DB_Username = "root";;
$DB_Password = "";;
$DB_DBName = "ishop";;
$DB_TBLName = "oi_mall_payment";;

$savename = date("YmjHis");
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect.");;
mysql_query("Set Names 'gbk'");
$file_type = "vnd.ms-excel";;
$file_ending = "xls";
header("Content-Type: application/$file_type;charset=big5");
header("Content-Disposition: attachment; filename=".$savename.".$file_ending");;
//header("Pragma: no-cache");;;;;

$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 die("Couldn't select database");;
$result = @mysql_query($sql,$Connect) or die(mysql_error())

echo("$titlen");;;
$sep = "t";;;
for ($i = 0; $i < mysql_num_fields($result); $i++) {
echo mysql_field_name($result,$i) . "t";;;
};;
print("n");;;
$i = 0;;;
while($row = mysql_fetch_row($result)) {;;
$schema_insert = "";
for($j=0; $j<mysql_num_fields($result);$j++) {;;
if(!isset($row[$j]));;
$schema_insert .= "NULL".$sep;;;
elseif ($row[$j] != "");;
$schema_insert .= "$row[$j]".$sep;
else;;
$schema_insert .= "".$sep;;;
};;
$schema_insert = str_replace($sep."$", "", $schema_insert);;;
$schema_insert .= "t";;;
print(trim($schema_insert));;;
print "n";;;
$i++;;;
};;
return (true)
?>
