ID: 32785 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Assigned Bug Type: Documentation problem Operating System: Debian GNU/Linux PHP Version: 4.3.10 Assigned To: nlopess New Comment:
The documentation does mention this: If the limit parameter is negative, all components except the last limit are returned. This feature was added in PHP 5.1.0. Sure the 5.1+ example could have a comment specifying this version requirement but no need to get all crazy! :) When the explode() docs get converted to the new doc style the change will be much clearer as each function now has a CHANGELOG. We document future versions too, it's the way it is. A more appropriate question is "why not" but anyway it's so people using the manual can handle/know future changes/additions, and that we don't forget to document these changes.
