The PHP site has good info at
http://us4.php.net/language.variables.variable

I don't use personally use them exactly like that.. But for forms when
you have an unknown number of items in say a radio group, they are
invaluable.

i.e.
<?
# to output
for($a=0;$a<5;$a++){
	echo "<input type='radio' name=radio_$a value=$a>\n";
}

#to read
for($a=0;$a<5;$a++){
	$reading = ${"radio_".$a}; // reading the variable variable
	#do something with $reading if it <> ""...
}
?>

That is just about the only way I ever use them, and commonly do use
them. However, the methods in the php.net examples would only serve to
confuse..
