(I don't think it's actually correct, but at least it's consistent). In PHP7 this only works when changing the property directly, but ReflectionProperty::setValue() only changes the attribute value for the child class. See #1 and #2 in the attached code. Test script: --------------- <?php class T1 { public static $data; public static function getDataBySelf() { return self::$data; } public static function getDataByStatic() { return static::$data; } } class T2 extends T1 {} $Prop1 = new ReflectionProperty(T1::class, 'data'); $Prop2 = new ReflectionProperty(T2::class, 'data'); // #1 // prints: hello, hello in PHP5, but world, hello in PHP7 - not OK $Prop1->setValue(\T1::class, "world"); $Prop2->setValue(\T2::class, 'hello'); // #2 // prints: hello, hello in both PHP5 and PHP7 - OK //T1::$data = "world"; //T2::$data = 'hello'; var_dump("T2::self = " . T2::getDataBySelf()); var_dump("T2::static = " . T2::getDataByStatic()); Expected result: ---------------- string(16) "T2::self = hello" string(18) "T2::static = hello" Actual result: -------------- string(16) "T2::self = world" string(18) "T2::static = hello" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71018&edit=1
