Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Previous Comments: ------------------------------------------------------------------------ [2017-12-01 15:29:07] peehaa@php.net Also is in the docs: > If the offset is larger than the size of the array then returns an empty array. Also it seems like you are confusing the length (3rd param) with the offset (2nd param) ------------------------------------------------------------------------ [2017-12-01 15:25:57] peehaa@php.net Always been like that: https://3v4l.org/tPsel ------------------------------------------------------------------------ [2017-12-01 15:22:08] nodex at icloud dot com Description: ------------ When using array_slice on a smaller array, PHP 7.1.4 (untested newer versions) returns a blank array if the size of the array is less than the $length parameter of array_slice In php 5.6 this was not the case, the function simply returned the entire array if it was shorter. Surely this must be a bug or are we now meant to count the array to check it's the right size before calling array_slice? Test script: --------------- # Basic reproduction test $array = range(0,10); $slice = array_slice($array,12); // same with and without the offset parameter! print_r($slice); // Empty! $array = range(0.5); $slice = array_slice($array,3); print_r($slice); // As expected 3 elements! ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75611&edit=1
