ReflectionMethod::setAccessible — Set method accessibility
Enables invoking of a protected or private method via the ReflectionMethod::invoke() method.
Hinweis: As of PHP 8.1.0, calling this method has no effect; all methods are invokable by default.
Es wird kein Wert zurückgegeben.
Beispiel #1 Simple Class definition
<?php
class MyClass
{
private function foo()
{
return 'bar';
}
}
$method = new ReflectionMethod("MyClass", "foo");
$method->setAccessible(true);
$obj = new MyClass();
echo $method->invoke($obj);
echo $obj->foo();
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
bar Fatal error: Uncaught Error: Call to private method MyClass::foo() from global scope in /in/qdaZS:16
This is handy for accessing private methods but remember that things are normally private for a reason! Unit Testing is one (debatable) use case for this.
Example:
<?php
class Foo {
private function myPrivateMethod() {
return 7;
}
}
$method = new ReflectionMethod('Foo', 'myPrivateMethod');
$method->setAccessible(true);
echo $method->invoke(new Foo);
// echos "7"
?>
