Exemples

Exemple #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

?>

L'exemple ci-dessus va afficher :

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"
}

Exemple #2 Example showcasing difference between ReflectionFunctionAbstract::getClosureCalledClass(), ReflectionFunctionAbstract::getClosureScopeClass(), and ReflectionFunctionAbstract::getClosureThis() with a static method

<?php

class A {
public function
getClosure() {

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

?>

L'exemple ci-dessus va afficher :

string(1) "B"
NULL
