Doc #70654 [NEW]: array_map key preservation behaviour not explicit

From: lucas at threeam dot com dot au Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:array_map key preservation behaviour not explicit Description: ------------ --- From manual page: http://www.php.net/function.array-map --- Not a dupe of, but related to #43612. The page says (too far down) that "If the array argument contains string keys then the returned array will contain string keys if and only if exactly one array is passed. If more than one argument is passed then the returned array always has integer keys." Whereas the actual behaviour is "The returned array will preserve the keys of the array argument if and only if exactly one array is passed. If more than one array is passed, the returned array will have sequential, integer keys." It would be great if this was official so we could rely on it. -- Edit bug report at https://bugs.php.net/bug.php?id=70654&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70654&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70654&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70654&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70654&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70654&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70654&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70654&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70654&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70654&r=support Expected behavior: https://bugs.php.net/fix.php?id=70654&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70654&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70654&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70654&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70654&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70654&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70654&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70654&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70654&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70654&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70654&r=mysqlcfg
