2.简单的输出excel文件

header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=test.xml"); 
header("Pragma:no-cache");
header('Expires:0');
echo "world"."\t";
echo "\t\n";
  
/*start of second line*/  
echo "this is second line"."\t";  
echo "Hi,pretty girl"."\t";  
echo "\t\n";
