note 92602 added to function.array-merge

In some situations, the union operator ( + ) might be more useful to you than array_merge. The array_merge function does not preserve numeric key values. If you need to preserve the numeric keys, then using + will do that. ie: <?php $array1[0] = "zero"; $array1[1] = "one"; $array2[1] = "one"; $array2[2] = "two"; $array2[3] = "three"; $array3 = $array1 + $array2; //This will result in:: $array3 = array(0=>"zero", 1=>"one", 2=>"two", 3=>"three"); ?> Note the implicit "array_unique" that gets applied as well. In some situations where your numeric keys matter, this behaviour could be useful, and better than array_merge. --Julian ---- Server IP: 209.41.74.194 Probable Submitter: 99.231.215.159 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/92602 Del: integrated -- https://master.php.net/note/delete/92602/integrated Del: useless -- https://master.php.net/note/delete/92602/useless Del: bad code -- https://master.php.net/note/delete/92602/bad+code Del: spam -- https://master.php.net/note/delete/92602/spam Del: non-english -- https://master.php.net/note/delete/92602/non-english Del: in docs -- https://master.php.net/note/delete/92602/in+docs Del: other reasons-- https://master.php.net/note/delete/92602 Reject -- https://master.php.net/note/reject/92602 Search -- https://master.php.net/manage/user-notes.php
