generally we are exporting excel or csv file,
here i want to do the same process in ms word document.

hai it is very simple please run these simple program
In the test.php type these coding
<a href="export.php">click here</a>
and save it after open the new page and save the file name as export.php
in the export.php file type this coding
<?php
$vExcelFileName="export". ".doc";
header("Content-type: application/x-ms-download"); //#-- build header to download the excel file
header("Content-Disposition: attachment; filename=$vExcelFileName");
header('Cache-Control: public');
echo "hai";
?>

so if u click the (click here) link in test.php means one window will open for open or saving the document file.
in the document file with the words (hai).


if u need to expotr the details to excel sheet means change the extension
for example
$vExcelFileName="export". ".xls";

thank u....................
