note 65992 added to function.array-merge-recursive

The documentation for array_merge_recursive() states that string keys are preserved while numeric keys are renumbered. What's not obvious is that string keys which happen to be numeric are NOT preserved, but renumbered: $a = array('5' => array('blue')); $b = array('5' => array('red')); $c = array_merge_recursive($a, $b); print_r($c); Output: Array ( [0] => Array ( [0] => blue ) [1] => Array ( [0] => red ) ) If the key '5' were treated as a string, the resulting array would be this: Array ( [5] => Array ( [0] => blue [1] => red ) ) ---- Server IP: 64.71.164.2 Probable Submitter: 65.106.184.146 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge-recursive.php Edit -- http://master.php.net/note/edit/65992 Del: integrated -- http://master.php.net/note/delete/65992/integrated Del: useless -- http://master.php.net/note/delete/65992/useless Del: bad code -- http://master.php.net/note/delete/65992/bad+code Del: spam -- http://master.php.net/note/delete/65992/spam Del: non-english -- http://master.php.net/note/delete/65992/non-english Del: in docs -- http://master.php.net/note/delete/65992/in+docs Del: other reasons-- http://master.php.net/note/delete/65992 Reject -- http://master.php.net/note/reject/65992 Search -- http://master.php.net/manage/user-notes.php
