Previous Comments: ------------------------------------------------------------------------ [2012-05-10 18:55:01] kenaniah at gmail dot com Description: ------------ Neither http://php.net/manual/en/class.closure.php nor http://www.php.net/manual/en/functions.anonymous.php mention that anonymous functions / lambdas bind the object they are defined in to $this, and that the automatic binding functionality can be avoided by declaring the lambda as static: <?php $lambda = static function() { ... } ?> There should probably be a warning about generating lambdas in object contexts as it silently binds a reference to the defining object, which could cause all sorts headaches when attempting to cause the destruction of an object. Defining a static lambda like the code sample above prevents the lambda from binding to its defining object. Please patch the documentation accordingly. Thanks! ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61999&edit=1
