#48119 [Ana]: usort() docs don't mention it now takes a lambda

ID: 48119 User updated by: schwern at pobox dot com Reported By: schwern at pobox dot com Status: Analyzed Bug Type: Documentation problem PHP Version: Irrelevant New Comment: If you're going to go with that method, which is fine, the docs need a few things to support it. 1. The docs on the callback type have to document it. Currently it does not. It says "A PHP function is passed by its name as a string." There's no mention of being able to use a lambda in 5.3.0. http://www.php.net/manual/en/language.pseudo-types.php#language.types.callback 2. Remove any mentions of the new 5.3.0 callback syntax from specific function documentation, such as array_map. The fact that array_map() documented it and usort() did not suggested it was an exceptional case. Previous Comments: ------------------------------------------------------------------------ [2009-05-02 02:00:43] kalle@php.net All functions that accept a callback can make use of lambda style functions, I don't think its worth adding to every single function that takes a callback parameter that as of 5.3 its possible to pass a closure there. I'll leave this to one of the other doc-geeks to decide. ------------------------------------------------------------------------ [2009-04-29 23:58:58] schwern at pobox dot com Description: ------------ The documentation for array_map() mentions... 5.3.0 It is now possible to use a lambda function as the callback. That's nice to know. usort() does not mention this, nor does it have any examples showing it off. It would be nice if it did. I had to compile up 5.3.0 to check that it did, in fact, work. There also appear to be no tests for this in ext/standard/tests/array/usort* ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48119&edit=1
