php将数据库导出成excel的方法

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);
?>
