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

<?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("$title\n");     
$sep = "\t";     
for ($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);  
?>
