I agree with the recommendation to just use an array. Variable variables
are almost always just a workaround for an array.
That being said, if you're creating the variable then you can create the
name. If you're saying
$a = 'x';
$b = 'y';
$c = 'z';
$xyz = 'foobar';
//Get name of "variable"
$name = $a.$b.$c; // $name = "xyz"
//Get value of variable
$value = ${$a.$b.$c}; // $value = "foobar"
Show some code if that doesn't clue you in.
