How to access a variable variable with a name containing spaces?

How does PHP handle something like this:

$blah = "Testing a variable"; 
$$blah = "test";

What would I access my dynamically declared variable?

Not really an answer, but...

<?php 
function I_love_you()
{
    return "haha";
}

$haha = "HoHoHo";
$tom = "I_love_you";
$blah = "tom";

echo ${$$blah()};
?>

echo ${'Testing a variable'};

However, you don't want to do this in practice. It makes for unmaintainable, bug-prone code.

The variable $blah must contain a valid variable name.

Everything you need to know about variable variables at http://www.php.net/manual/en/language.variables.variable.php, except for one thing: don't use them.
