Description:
------------
This little script 

      1
      2 <?php
      3 session_start();
      4 ?>
      5 session inizializzata

must to be produce a warning (line 1 is empty so something is send to header). But there is a problem: there are 2 warning:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/httpd/html/LIBRO/sessioni/1.php:2) in /home/httpd/html/LIBRO/sessioni/1.php on line 3

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/httpd/html/LIBRO/sessioni/1.php:2) in /home/httpd/html/LIBRO/sessioni/1.php on line 3
session inizializzata


I have no php.ini set, so there is the default.

Some value from phpinfo():

display_errors => On => On
display_startup_errors => Off => Off
error_append_string => no value => no value
error_log => no value => no value
error_prepend_string => no value => no value
error_reporting => no value => no value
html_errors => Off => On
ignore_repeated_errors => Off => Off
log_errors => Off => Off
log_errors_max_len => 1024 => 1024
track_errors => Off => Off

session.auto_start => Off => Off
session.cookie_domain => no value => no value
session.cookie_lifetime => 0 => 0
session.cookie_path => / => /
session.cookie_secure => Off => Off

bye
