What you've got written there will make the condition true if either
$k=="Phone_Number", or if "Cell_Phone" is true, and "Cell_Phone" is a
string that is always true.
I think this may be what you're looking for:
if ($k == "Phone_Number" || $k == "Cell_Phone")
You can use either "OR" operator ("or"/"||") in this case. They both mean
the same thing, but the || has higher precedence. In particular, if you
have an assignment of some variety (=, +=, etc), the || will bind tighter
than the assignment, and the "or" will not:
$a = 0 || 1;
will set $a to 0 and evaluate to 1, but
$a = 0 or 1;
will set $a to 1 and evaluate to 1.
Is that right? Can someone confirm that?
