#46765 [NEW]: array_merge documentation incorrectly states that "arrays will be preserved"

From: charonme at yahoo dot com Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: array_merge documentation incorrectly states that "arrays will be preserved" 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 bug report at http://bugs.php.net/?id=46765&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46765&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46765&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46765&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46765&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46765&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46765&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46765&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46765&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46765&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46765&r=support Expected behavior: http://bugs.php.net/fix.php?id=46765&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46765&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46765&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46765&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46765&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46765&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46765&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46765&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46765&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46765&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46765&r=mysqlcfg
