Sometimes
it is convenient to be able to have variable variable (var vars)
names. That is, a variable name which can be set and used
dynamically.Var vars can be very handy, you can use them to associate a name to a variable.
<?
$my_soon_to_be_variable = 'wow_my_variable';
$$my_soon_to_be_variable = 'Now it's a VAR VAR'; // It's a var varecho $wow_my_variable; // That's right, it's a variable
?>
