Doc #51699 [Opn->Csd]: array_merge() reindexes multiple arrays - doc error

Edit report at http://bugs.php.net/bug.php?id=51699&edit=1 ID: 51699 Updated by: salathe@php.net Reported by: stevenrusch at gmail dot com Summary: array_merge() reindexes multiple arrays - doc error -Status: Open +Status: Closed Type: Documentation Problem Package: Documentation problem Operating System: WinXp PHP Version: Irrelevant -Assigned To: +Assigned To: salathe New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. That sentence has been rephrased to read, "If all of the arrays contain only numeric keys, the resulting array is given incrementing keys starting from zero." Hopefully that makes more sense; please give feedback if not. Thank you for your report.

The "If only one array is given" is incorrect. I supplied two arrays, both numerically indexed, and the result was reindexed (as also shown in Example#3). The sentence implies this would not happen if multiple numerically indexed arrays were given because it says "if only one...". The documentation should state: "If one or more arrays are given in which all arrays contain only numeric keys, the array values are merged and the keys are reindexed starting with zero in a continuous way." or something to that effect. I realize Example #3 somewhat shows this by supplying two arrays one of which is empty and it shows the reindex. It would still be nice if the wording in the description above matched this. As you guessed, I read the doc description, used it, debugged my problem, and THEN noticed Example #3. Test script: --------------- $array1 = array(10=>'Ten',11=>'eleven'); $array2 = array(5=>'five',16=>'sixteen'); var_dump(array_merge($array1,$array2)); Expected result: ---------------- array(4) { [10]=> string(3) "Ten" [11]=> string(6) "eleven" [5]=> string(4) "five" [16]=> string(7) "sixteen" } Actual result: -------------- array(4) { [0]=> string(3) "Ten" [1]=> string(6) "eleven" [2]=> string(4) "five" [3]=> string(7) "sixteen" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51699&edit=1
