With this code I'm trying to test if I can call certain functions
if (method_exists($this, $method))
$this->$method();
however now I want to be able to restrict the execution if the $method is protected, what would I need to do?
You'll want to use Reflection.
class Foo {
public function bar() { }
protected function baz() { }
private function qux() { }
}
$f = new Foo();
$f_reflect = new ReflectionObject($f);
foreach($f_reflect->getMethods() as $method) {
echo $method->name, ": ";
if($method->isPublic()) echo "Public\n";
if($method->isProtected()) echo "Protected\n";
if($method->isPrivate()) echo "Private\n";
}
Output:
bar: Public
baz: Protected
qux: Private
You can also instantiate the ReflectionMethod object by class and function name:
$bar_reflect = new ReflectionMethod('Foo', 'bar');
echo $bar_reflect->isPublic(); // 1
