Doc #62804 [NEW]: array_slice(): Undocumented huge difference in behavior of across 5.2.4

From: matteosistisette at gmail dot com Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:array_slice(): Undocumented huge difference in behavior of across 5.2.4 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 bug report at https://bugs.php.net/bug.php?id=62804&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62804&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62804&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62804&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62804&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62804&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62804&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62804&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62804&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62804&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62804&r=support Expected behavior: https://bugs.php.net/fix.php?id=62804&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62804&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62804&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62804&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62804&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62804&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62804&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62804&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62804&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62804&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62804&r=mysqlcfg
