Bug #18315 Updated: Different behaviour of array_diff in a variables and encapsuled with each

ID: 18315 Updated by: cirello@estadao.com.br Reported By: cirello@estadao.com.br Status: Bogus Bug Type: Arrays related Operating System: Linux Red Hat Linux release 7.1 PHP Version: 4.2.1 New Comment: OK, if it is not a bug on array_diff there must be some problem somewhere. A deeper look on the possibilities I understand that the problem might be layed on each function. Anyway I shall discuss it on newsgroup first... Then I'll apply for another bug check or not. Thank you.
