My PHP generated CSV file is saving as a PHP file - php

Question

I've learned how to create CSV files from MySQL data from another StackOverflow question. My problem is, for some reason when I call this code, it tries to save a file called index.php (which is the current page). Inside the index.php file my data from the table is there, separated by commas. I'm guessing I have a small typo somewhere, but after playing with the code I cannot find it. Thanks to anyone who can help.
$result=mysql_query("SELECT * from tbl_email");
if(mysql_num_rows($result)) {
header ("Content-type: application/csv Content-Disposition:\"inline; filename=messages.csv\"");
echo "REF #,Company,Name,Email,Message,Date\n";
while($row = mysql_fetch_row($result)) {
$companyname = mysql_query("SELECT company FROM tbl_users WHERE user_id ='$row[1]'");
$datname = mysql_fetch_array($companyname);
echo"$row[7],$datname[company],$row[2],$row[4],$row[5],$row[6]\n";
}
die();
}

Answer 1

You need multiple header() calls rather than one call which supplies multiple headers on a single line, and I believe the most appropriate mime type for a CSV is text/csv.
header("Content-type: text/csv");
header("Content-Disposition: inline; filename=messages.csv");
And more commonly, we would use Content-Disposition: attachment to force a download.
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=messages.csv");

Answer 2

It should be:
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename="messages.csv"');
Notice that the value for filename is not encased correctly with double quotes. Try to use single quotes in php, this will save you alot of trouble. ;)
