Req #54311 [Com]: Implicit variable scope declaration

Edit report at https://bugs.php.net/bug.php?id=54311&edit=1 ID: 54311 Comment by: dan dot lugg at gmail dot com Reported by: dan dot lugg at gmail dot com Summary: Implicit variable scope declaration Status: Wont fix Type: Feature/Change Request Package: *Programming Data Structures Operating System: Windows 7 x64 PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Thank you for your response Rasmus. I can understand the motivation to restrict "scope inheritance", especially with the introduction of closure rebinding (which I must say, I am excited to use in production) Hopefully closure rebinding will afford me the functionality that was sought after with this request. All the same, thank you for your consideration. :) Previous Comments: ------------------------------------------------------------------------ [2012-03-05 06:18:50] rasmus@php.net I really prefer to be explicit about what you bring into a restricted scope. That has been PHP's approach from day 1 with the explicit nature of the 'global' keyword to declare explicitly which global variables a function will muck with. And in PHP 5.4 with the implicit binding of $this I think most of the motivation for a request like this is gone anyway. ------------------------------------------------------------------------ [2011-03-19 18:14:33] dan dot lugg at gmail dot com Further examples exhibiting scope inheritance: class Test{ public $func; public function callFunc(){ $this->func(); } } $foo = 'hello'; $test = new Test; $test->func = function() use implicit{ echo $foo; } $test->callFunc(); // hello ------------------------------------------------------------------------ [2011-03-19 04:14:28] dan dot lugg at gmail dot com Description: ------------ Feature request for 'use implicit', or semantically similar syntax. Anonymous functions with the use implicit directive inherit all variables from parent scope in which they are declared, not called; $foo = 'hello'; call_user_func(function() use implicit{ echo $foo; // hello }); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54311&edit=1
