ReflectionFunctionAbstract::getClosureCalledClass — Returns the class corresponding to static:: inside a closure
Returns the class as a ReflectionClass that
corresponds to static:: inside the
Closure.

Returns a ReflectionClass corresponding to the class
represented by static:: in the Closure.
If the function is not a closure or if it has global scope null

Example #1 Example showcasing difference between ReflectionFunctionAbstract::getClosureCalledClass(), ReflectionFunctionAbstract::getClosureScopeClass(), and ReflectionFunctionAbstract::getClosureThis() with an instance method
<?php
class A {
public function getClosure() {
var_dump(self::class, static::class);
return function () {
};
}
}
class B extends A {
}
$b = new B();
$c = $b->getClosure();
$r = new ReflectionFunction($c);
var_dump($r->getClosureThis()); // $this === $b
var_dump($r->getClosureScopeClass()); // self::class
var_dump($r->getClosureCalledClass()); // static::class
?>The above example will output:
string(1) "A"
string(1) "B"
object(B)#1 (0) {
}
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "A"
}
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "B"
}
Example #2 Example showcasing difference between ReflectionFunctionAbstract::getClosureCalledClass(), ReflectionFunctionAbstract::getClosureScopeClass(), and ReflectionFunctionAbstract::getClosureThis() with a static method
<?php
class A {
public function getClosure() {
var_dump(self::class, static::class);
return static function () {
};
}
}
class B extends A {
}
$b = new B();
$c = $b->getClosure();
$r = new ReflectionFunction($c);
var_dump($r->getClosureThis()); // NULL
var_dump($r->getClosureScopeClass()); // self::class
var_dump($r->getClosureCalledClass()); // static::class
?>The above example will output:
string(1) "A"
string(1) "B"
NULL
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "A"
}
object(ReflectionClass)#4 (1) {
["name"]=>
