Previous Comments: ------------------------------------------------------------------------ [2012-10-26 16:14:48] dagguh at gmail dot com Another proof that LSB produces bad code. Just look at it. There is no such thing as static inheritance, so maybe you should simply learn to code. ------------------------------------------------------------------------ [2012-05-11 21:05:49] ash at itsash dot co dot uk I have the same issue on 5.3.6 on Ubuntu. static::$classVariable with late static binding causes php to override the parent static variable. When using static $methodVariable = 'first_value'; if this is later changed, by $methodVariable, when a new instance of that class is initiated, the $methodVariable SHOULD be 'first_value', however UNEXPECTEDLY it carries over from any prior instance. ------------------------------------------------------------------------ [2010-10-27 02:54:21] felipe@php.net Probably related to bug #48623 ------------------------------------------------------------------------ [2010-10-25 21:41:26] frederic dot hardy at mageekbox dot net Description: ------------ when a class which extends a parent class with a method which define a static variable is created then a condition is verified, the static variable is not reset in the chield class. Test script: --------------- <?php abstract class singleton { public static function getInstance() { static $instance = null; if ($instance === null) { $instance = new static(); } return $instance; } protected function __construct() {} protected function __clone() {} } class a extends singleton { } var_dump(a::getInstance()); if (1 > 0) { class b extends a {} } var_dump(b::getInstance()); ?> Expected result: ---------------- object(a)#1 (0) { } object(b)#2 (0) { } Actual result: -------------- object(a)#1 (0) { } object(a)#1 (0) { } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=53155&edit=1
