Addresses bug #46765. ------------------------------------------------------------------------ [2008-12-05 14:29:58] charonme at yahoo dot com Description: ------------ Related bug: http://bugs.php.net/bug.php?id=42323 array_merge documentation states: "If you want to completely preserve the arrays and just want to append them to each other (not overwriting the previous keys), use the + operator" However, both arrays (plural) are not preserved, only the first array (singular) is preserved and the second array is NOT preserved if there are some keys that are already defined in the first array. The documentation needs to be clear enough to state that the second array might not be preserved at all even though the first array (singular) will always be preserved. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46765&edit=1
