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 

以下为引用的内容： <?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
