php class syntax

[spritch2]

if Mail.php is a class file from pear and $sender becomes an new object can anyone explain the following syntax:-

$sender =& Mail::factory('mail');

the book i'm reading doesnt explain the difference between the above and the usual way of creating an instance

thanks

ps forgot to mention Mail.php is included further up the script

[spritch2]

ahh, got it

Create the mail object using the Mail::factory method

was getting stuck on the =& ..too tired to realise what i was lookin at!
