PHP生成Excel，然后另存为的方法

1.以下方法是直接下载（显示另存为）一个test1.xls的Excel表。

<?
header("Content-type:application/xls");
header("Content-Disposition:attachment;filename=test1.xls");

echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
?>

2.下面是直接在IE中打开Excel表的header

<?
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=test.xls");

echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
?>
