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
