hi,
curly braces are useful to specify in a double quoted string where is the
end of the variable name.
"$ciao" == "${ciao}"
in case of associative arrays is recommended to prevent the parser to mess
up.
see php manual at the following section for details

Oggetto: RE: R: [PHP] Get "nice" variables from POST
I try to use quotes in the query and this doesn't work.
$query = "SELECT * FROM user WHERE user_id = '$_POST['user_id']}'";
But you use brackets and it works.. Why do you use brackets ?
$query = "SELECT * FROM user WHERE user_id = ${_POST['user_id']}";
