	$msg = str_replace("b","o", $lol);
	$msg = str_replace("c","p", $lol);
	$msg = str_replace("d","q", $lol);
	$msg = str_replace("e","r", $lol);

Misschien alle $lol's vervangen door $msg. Anders wordt er alleen de n door de z vervangen.

Wat je uiteindelijk wil doen gelijkt heel hard op atbash, alleen ga ik je zeggen dat dit geen encrypt functie zal zijn.

Waarom niet: het is onmogelijk de omgekeerde waarde te vinden:

"banaan"
==>
"ozzzzz"

"baanan"
==>
"ozzzzz"

"baaaan"
==>
"ozzzzz"

"bnnnnn"
==>
"ozzzzz"

ozzzzz
ozzzzz
ozzzzz
ozzzzz
ozzzzz

Niet echt omkeerbaar dunkt me.
