Description
It appears that the behavior of get_class_vars has changed between 8.0 and 8.1
- 8.0:
get_class_varsyields the current value of the static variables (even if documentation says, it is the default value) - 8.1:
get_class_varsyields the default value according to the documentation
try it out in https://onlinephp.io/c/5779d
<?php
class Foo {
static $bar = "bar";
}
echo Foo::$bar;
var_dump(get_class_vars(Foo::class));
Foo::$bar = "foobar";
var_dump(get_class_vars(Foo::class));
