Hi,
You could see it this way : getPrototype() will get you the information on
where your function has been "declared" in the first place. If we extend your
example:
<?php
class Hello {
public function sayHelloTo($name) {
}
}
class HelloWorld extends Hello {
public function sayHelloTo($name) { }
public function sayHi() { }
}
class HelloUniverse extends HelloWorld {
public function sayHelloTo($name) { }
}
/*
* Will output: Hello::sayHelloTo
*/
$reflectionMethod = new ReflectionMethod('HelloUniverse', 'sayHelloTo');
$prototype = $reflectionMethod->getPrototype();
echo $prototype->class . '::' . $prototype->name;
/*
* Will throw an exception
*/
$reflectionMethod = new ReflectionMethod('HelloWorld', 'sayHi');
$prototype = $reflectionMethod->getPrototype();
echo $prototype->class . '::' . $prototype->name;
So in the case of sayHelloTo() , the prototype is Hello::sayHelloTo. And in the
other case, there is no prototype for sayHi(), generating the exception. It
explains also why trying to get the prototype on Hello doesn't work.
You should get the result you want by doing:
echo $reflectionMethod->getDeclaringClass()->getName() . "::" .
$reflectionMethod->getName();

Subject: [PHP-DEV] Bug in reflectionMethod::getPrototype() ?
Hello !
During french PHP test fest, i have tested
ReflectionMethod::getPrototype(), and the result is... strange.
This is the PHPT file :
--TEST--
--FILE--
<?php
class Hello {
public function sayHelloTo($name) {}
}
class HelloWorld extends Hello {
public function sayHelloTo($name) {}
}
$reflectionMethod = new ReflectionMethod('HelloWorld', 'sayHelloTo');
$prototype = $reflectionMethod->getPrototype();
echo $prototype->class . '::' . $prototype->name;
?>
--EXPECT--
Hello::sayHelloTo
In my opinion, result is strange because i'm expecting
HelloWorld::sayHelloTo instead of Hello::sayHelloTo.
More strange, if i'm using 'Hello' as class instead of 'HelloWorld' as
first argument of ReflectionMethod constructor,
ReflectionMethod::getPrototype() throw an exception because for PHP,
Hello::sayHelloTo() method has no prototype...
So, i think there is a problem.
Your opinion ?
Best regards,
Fred
