Sessions Again

[Arnold Shore]

In Win32, php4: (I don't have access to the php.ini file.)

With 'session_start( )', how do I avoid the complaint "PHP Notice: A session
had already been started" ?
Without 'session_start( )', I get the "Undefined variable: _SESSION "
complaint.

Any hope? (I'll be happy simply to suppress the error message, although I AM
trying to understand what's behind it.).

Thanks, all.

Normally this happens when the session.auto_st art directive has been enabled
in the php.ini file while calling session_start() .

This should not happen when you do a simple "print_r($_SESS ION)" on top of
your script and sounds like a configuration problem. Ask your administrator
about this.

Prepending an at-sign will surpress the notice:

@session_start( );

Try this on top of your code:

ini_set('sessio n.auto_start', '0');

I haven't tested but may do the trick. In any case, it'd be interesting to
see the actual code that claims about $_SESSION being undefined, because
when you start a session twice the exact notice is:

A session had already been started - ignoring session_start()

"Ignoring" sounds like, well, no point in using that code :-?

Maybe you're trying to do session_start() more than once.

Try this:
<?php
echo 'ini_get('sessi on.auto_start') is ',
ini_get('sessio n.auto_start'), "<br>\n";
echo 'before session_start() session_id() returns ', session_id(),
"<br>\n";

// You may want to replace your session_start() s with this too
if (!session_id()) session_start() ;

echo 'after session_start() session_id() returns ', session_id(),
"<br>\n";
?>
