#42323 [NEW]: Details in array_merge page are wrong

From: kev at projectcolo dot org dot uk Operating system: N/A PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Details in array_merge page are wrong Description: ------------ The notes in Example 257 above are incorrect. It states: If you want to completely preserve the arrays and just want to append them to each other, use the + operator Check the array type page at http://www.php.net/manual/en/language.types.array.php which states differently. Duplicate keys are ignored with the + operator. Reproduce code: --------------- <?php $x = array('moon','sky'); $y = array('rain','shine'); var_dump($x + $y); var_dump(array_merge($x, $y)); ?> Expected result: ---------------- array(2) { [0]=> string(4) "moon" [1]=> string(3) "sky" ... more values } array(4) { [0]=> string(4) "moon" [1]=> string(3) "sky" [2]=> string(4) "rain" [3]=> string(5) "shine" } Actual result: -------------- array(2) { [0]=> string(4) "moon" [1]=> string(3) "sky" } array(4) { [0]=> string(4) "moon" [1]=> string(3) "sky" [2]=> string(4) "rain" [3]=> string(5) "shine" } -- Edit bug report at http://bugs.php.net/?id=42323&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42323&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42323&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42323&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42323&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42323&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42323&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42323&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42323&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42323&r=support Expected behavior: http://bugs.php.net/fix.php?id=42323&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42323&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42323&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42323&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42323&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42323&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42323&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42323&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42323&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42323&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42323&r=mysqlcfg
