excel dump

Hallo,
Ik heb onderstaand scriptje op het internet gevonden (http://fundisom.com/phparadise/php/databases/mySQL_to_excel) voor een excel dump uit mysql.
Ik ondervind het probleem dat bij het uitvoeren vh script ik het resultaat in mijn internetbrowser te zien krijg, en dus niet in excel.
Weet er iemand waaraan het zou kunnen liggen?

//EDIT YOUR MySQL Connection Info:
$DB_Server = "localhost"; //your MySQL Server
$DB_Username = ""; //your MySQL User Name

//$DB_TBLName, $DB_DBName, may also be commented out & passed to the browser
//as parameters in a query string, so that this code may be easily reused for
//any MySQL table or any MySQL database on your server
