示例 #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
?>以上示例会输出：
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"
}
示例 #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
?>以上示例会输出：
string(1) "A"
string(1) "B"
NULL
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "A"
}
object(ReflectionClass)#4 (1) {
