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";

$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("$title ");    
$sep = " ";    
for ($i = 0; $i < mysql_num_fields($result); $i++) {
    echo mysql_field_name($result,$i) . " ";    
}    
print(" ");    
$i = 0;    
while($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 .= " ";
