Edit report at https://bugs.php.net/bug.php?id=62804&edit=1 ID: 62804 Comment by: alvaro at demogracia dot com Reported by: matteosistisette at gmail dot com Summary: array_slice(): Undocumented huge difference in behavior of across 5.2.4 Status: Open Type: Documentation Problem Package: Documentation problem PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Possible workaround: <?php $foo = array_slice($bar, 1, count($bar)-1, TRUE); ?> Previous Comments: ------------------------------------------------------------------------ [2012-08-12 20:06:33] matteosistisette at gmail dot com Description: ------------ --- From manual page: http://www.php.net/function.array-slice#refsect1- function.array-slice-description --- array array_slice ( array $array , int $offset [, int $length = NULL [, bool $preserve_keys = false ]] ) That the default value of the $length parameter is NULL is true only for php >=5.2.4 Prior to that version, passing NULL is NOT the same as omitting it. Check this: http://3v4l.org/gW4pG Note the difference in output between 5.2.3 and 5.2.4 Only starting from 5.2.4 it is as documented. This has a TREMENDOUS impact and must be documented with a gigantic red warning. Instead, it is not even mentioned. The sentence "If it is omitted, then the sequence will have everything from offset up until the end of the array." _is_ correct for all version, but if one needs to specify the $preserve_keys parameter without specifying $length, one needs to pass the default value (that's why it's very relevant), and the value has changed. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62804&edit=1
