that has almost the same meaning of
$_ = '_POST';
echo count($$_);
which again, for readability brackets are suggested to improve
maintainability
$_ = '_POST';
echo count(${$_});

I don't think it is about readability:
$arr[3] = 'test';
$test = 3;
//This prints "$test"
echo "This doesn't work: $$arr[3]";
//This prints 3
echo "This works: ${$arr[3]}";
Using the same type way as before in this thread.
My point is that in the curly braces you protect the way the evaluation
is going to be made into the string. So you can put them anywhere as
long as it is meaningful.
See some examples:
http://php.net/manual/en/language.types.string.php
in the complex (curly) syntax section.
