note 86379 added to language.operators.array

The union operator did not behave as I thought it would on first glance. It implements a union (of sorts) based on the keys of the array, not on the values. For instance: <?php $a = array('one','two'); $b=array('three','four','five'); //not a union of arrays' values echo '$a + $b : '; print_r ($a + $b); //a union of arrays' values echo "array_unique(array_merge($a,$b)):"; // cribbed from http://oreilly.com/catalog/progphp/chapter/ch05.html print_r (array_unique(array_merge($a,$b))); ?> //output $a + $b : Array ( [0] => one [1] => two [2] => five ) array_unique(array_merge(Array,Array)):Array ( [0] => one [1] => two [2] => three [3] => four [4] => five ) ---- Server IP: 209.41.74.194 Probable Submitter: 66.92.171.226 ---- Manual Page -- http://www.php.net/manual/en/language.operators.array.php Edit -- https://master.php.net/note/edit/86379 Del: integrated -- https://master.php.net/note/delete/86379/integrated Del: useless -- https://master.php.net/note/delete/86379/useless Del: bad code -- https://master.php.net/note/delete/86379/bad+code Del: spam -- https://master.php.net/note/delete/86379/spam Del: non-english -- https://master.php.net/note/delete/86379/non-english Del: in docs -- https://master.php.net/note/delete/86379/in+docs Del: other reasons-- https://master.php.net/note/delete/86379 Reject -- https://master.php.net/note/reject/86379 Search -- https://master.php.net/manage/user-notes.php
