I posted this previously; but the subject was misleading.
I could use one additional clarification regarding good practice.
As I understand the php manual the following is acceptable and I assume good practice.
$foo= TRUE;
if($foo) do.............. ; where $foo is a binary; but not a variable.
isset should be used for variables, such as;
isset($var) for variables and be careful with $var= ' '; etc. because $var is assigned, i.e., "set".
