ReflectionFunctionAbstract::getClosureCalledClass — Returns the class corresponding to static:: inside a closure
Returns the class as a ReflectionClass that
corresponds to resolving the class name corresponding to static:: inside the
Closure.
Esta função não possui parâmetros.
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
is returned instead.
Exemplo #1 Example showcasing difference between ReflectionFunctionAbstract::getClosureCalledClass(), ReflectionFunctionAbstract::getClosureScopeClass(), and ReflectionFunctionAbstract::getClosureThis() with a closure in the object context
<?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 === $b, since a non-static closure take the object context
var_dump($r->getClosureScopeClass()); // Corresponds to the self::class resolution inside a closure
var_dump($r->getClosureCalledClass()); // Corresponds to the static::class resolution inside a closure
?>O exemplo acima produzirá:
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"
}
Exemplo #2 Example showcasing difference between ReflectionFunctionAbstract::getClosureCalledClass(), ReflectionFunctionAbstract::getClosureScopeClass(), and ReflectionFunctionAbstract::getClosureThis() with a static closure without an object context
<?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, since the pseudo-variable $this is not available in a static context
var_dump($r->getClosureScopeClass()); // Corresponds to the self::class resolution inside a closure
var_dump($r->getClosureCalledClass()); // Corresponds to the static::class resolution inside a closure
?>O exemplo acima produzirá:
string(1) "A"
string(1) "B"
NULL
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "A"
}
object(ReflectionClass)#4 (1) {
["name"]=>
string(1) "B"
