Get all methods - php

Question

I'm attempting to build a role based access control in our PHP framework. The framework is on MVC architecture so every path works on /controller/action/param. We can get the controller and action on initialization and store them in variables, $controller, $action. Now my idea is to use a class to check the permissions of this action like:
Auth::permissions($controller, $action);
Now I'm hoping I could somehow create a script which would find all public methods of controllers inside a /modules/ folder. This way I could just run a script and it would update all controller actions as a list to the database, where we would get the role permissions from. This way I could avoid inserting all controller actions manually. Getting all the controllers is very easy as the folder structure is as:
/modules
/controller
controller.php
So I can just find all subdirectories on modules and add .php in the end. My question is that can I get the file's public methods somehow?
class Example extends Controller {
public function main() {
return 'foo';
}
}
This way I could store this in the database as
example | main | role_id

Answer 1

Here is a little code that can help you:
<?php
class Example {
public function main() {
return 'foo';
}
private function privatefunc(){
}
public function anotherpublicfunc(){
}
}
$reflector = new ReflectionClass("Example");
foreach($reflector->getMethods() as $method){
if($method->isPublic()) {
echo "Method ".$method->name." is public".PHP_EOL;
}else{
echo "Method ".$method->name." is not public".PHP_EOL;
}
}
?>
output:
Method main is public
Method privatefunc is not public
Method anotherpublicfunc is public

If you want to get public methods of a class then you can use get_class_methods read the doc here
class Car {
public function permission_method_two() {
}
public function permission_method_three() {
}
private function private_function() {
}
}
echo '<pre>'.print_r(get_class_methods('Car'),1).'</pre>';
// prints only public methods:
Array
(
[0] => permission_method_two
[1] => permission_method_three
)

Answer 3

You can follow convention:
- each public methods start without lowdash
- each private and protected method start with lowdash
Example
class Example
{
public function publicMethod()
{
}
private function _privateMethod()
{
}
protected function _protectedMethod()
{
}
}
and then use http://php.net/manual/ru/function.get-class-methods.php
foreach(get_class_methods('Example') as $methodName){
if(strpos($methodName, '_') !== 0) $publicMethod[] = $methodName;
}
