Exporting MySQL data to an RTF template creating multiple pages - mysql

Question

The data pulled from the database inserts into an RTF template without a problem as long as I only have 1 row. If I put my header("Content-type: text/rtf") inside the loop, however, I receive a headers already sent error. When removing the headers from the code, the raw data prints properly in the browser window.
How do I combine data from multiple records in the database to create multiple documents (or 1 document with page breaks)?
Code here:
$document='../docs/letter.rtf';
$qry="Select * from table";
$result=mysql_query($qry);
$num_row=mysql_num_rows($result);
while($row=mysql_fetch_assoc($result)){
$account_id=$row['pk_account];
$name=$row['first_name'];
$file_doc='01-'.$pk_account.'.rtf';
....
$body=file_get_contents($document);
$body=str_replace("NAME", $name, $body);
....
for($i=0; $i<$num_rows; $i++){
}
header("Content-type: text/rtf");
header("Content-Disposition:attachment; filename={$file_doc}");
echo $body;
}

Answer 1

You need to concatenate your $body. So instead of this:
$body=file_get_contents($document);
$body=str_replace("NAME", $name, $body);
try this:
$body.=str_replace("NAME", $name, file_get_contents($document));
Then place this outside your while loop:
header("Content-type: text/rtf");
header("Content-Disposition:attachment; filename={$file_doc}");
echo $body;
