A couple of days ago I placed a post regarding using the $_POST[]
variable in an insert sql query.  Both

$sql="insert into $table set Name = '".$_POST['elementName']."'";
$sql="insert into $table set Name = '{$_POST['elementName']}'";

worked perfectly.  Thanks to everyone for your help.  My question now is
regarding the curly brackets in the 2nd example.  Can anyone describe
why using the curly brackets works and/or how php processes them.  I
have read quite a bit about php and never come accross thier use in this
way.  Thanks again.
