[PHP] dynamic variable headache

[ROBERT MCPEAK]

My newbie brain is maxed out on this, and I'm sure one of you more experience guys can 
quickly straighten me out.

I've got a variable:

$_mmdd =  a_date_value;

Later, I've got four variables;

$foo= _;
$bar=;
$bleh=mm;
$doh=dd;

I want to stick these variables together on the fly to get _mmdd  and use that 
value as a variable name to return a_date_value.

It would be the equivalent of,

echo $foo$bar$bleh$doh;

That would give me a_date_value

I've read the docs on dynamic variables but still can't seem to break through mentally 
on this one.  Can you clear this up for me?

Thanks in advance.

Robert,

try reading about arrays instead. Variable variables are not a good idea
to use because your code would soon become such a mess that one year
later you will hate yourself seeing the code sputting frequently onto
the monitor and making crosses of your fingers as to the Satan's
appearance.

Arrays can do it all. Variable variables are only needed in really,
really few occasions.

$s = $foo . $bar . $bleh . $doh;
echo $$s; //will give you a_date_value
