ReflectionClass::hasConstant
A way to check if you can call an method over a class:
<?php
function is_public_method(
/* string */$className,
/* string */$method
){
$classInstance = new ReflectionClass($className);
if ($classInstance->hasMethod($method)) {
return false;
}
$methodInstance = $instance->getMethod($method);
return $methodInstance->isPublic();
}
?>

}
protected function protectedFoo() {
return true;
}
private function privateFoo() {
return true;
}
static function staticFoo() {
return true;
}
}
$rc = new ReflectionClass("C");
var_dump($rc->hasMethod('publicFoo'));
var_dump($rc->hasMethod('protectedFoo'));
var_dump($rc->hasMethod('privateFoo'));
var_dump($rc->hasMethod('staticFoo'));
// C should not have method bar
var_dump($rc->hasMethod('bar'));
// Method names are case insensitive
var_dump($rc->hasMethod('PUBLICfOO'));
?>

Parent methods (regardless of visibility) are also available to a ReflectionObject. E.g.,
<?php
class ParentObject {
public function parentPublic( ) {
}
private function parentPrivate( ) {
}
}
class ChildObject extends ParentObject {
}
$Instance = new ChildObject();
$Reflector = new ReflectionObject($Instance);
var_dump($Reflector->hasMethod('parentPublic')); // true
var_dump($Reflector->hasMethod('parentPrivate')); // true
?>
