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
