Re: [Phpwebsite-developers] Using session information to limit mailings...

[Matthew M. <ma...@tu...>]

php.net has probably the best information on this subject.

Briefly, you place information in a session like so:

$_SESSION['variable_name_here'] = "foo";

This session will remain until the user logs off or until you destroy
it.

You then access it just like you would any other variable.

$bar = $_SESSION['variable_name_here'];

echo $bar;

// prints 'foo'
