Possible Duplicate:
header() error not shown in php

My /etc/php5/apache2/php.ini file has the next configuration:

display_errors = On
log_errors = On
error_reporting = E_ALL | E_STRICT

and I can view errors like Undenifed variable, Parse error and so on in the browser, but with the next code

<!DOCTYPE html>
<?php
   header('hola: adios');
?>

I can’t see the Headers already sent error. Also with the Developer tools of Chrome I can see that the header hola: adios is set.
How could I see those type of errors?
Thanks.

    It is not showing you an error because it is NOT!
    the function is 

    header(string,replace,http_response_code)

    where string may be anything you wanna set as a header field:value. There isn’t a list what can be used or what not. You can always have custom header fields.

    check the manual – http://php.net/manual/en/function.header.php.

    <?php
header('inappropriate stuff');
?>

    try this and you wont be getting anything in header packet since php can’t find a colon ‘:’ as a separator inside the string which separates the header field from the value.

    NOTE: If you plan to use it with session, session_start() must be the first function to run at the beginning of your execution.
