About using session

session| Error Please see detailed error program and output result
?
echo "Testing ... ";
Session_Start ();
?>

Output is
Testing ...
Warning:cannot send session Cookie-headers already sent by (output started at f:php2000test.php:2) in f:php2000test.php On line 4

Warning:cannot Send session Cache Limiter-headers already sent (output started at f:php2000test.php:2) in F:php2000test . PHP on line 4

Analysis:
The main reason is that php.ini has a definition of session, by default, by using cookies
[Session]
Session.use_cookies = 1; Whether to use cookies

This means that cookies are stored in session and cookies must be set before the official HTM, that is, only within header, so this error occurs

We modify the program to
?
echo "Testing ... ";
Session_Start ();
?>
The same error, because Echo has already exported

We modify the program to
?
$i = 1;
Session_Start ();
?>
Running correctly indicates that there can be a calculation statement in front of the session_start, but no output statements

I tried to modify it.
session.use_cookies = 0; Whether to use cookies
But did not succeed, want to know the answer friend informed me, how to remove the cookie method session
