Check variable is public php

Question

I want to check if a local variable in a class is public or private. The reason is to create a function like this:

function ToArray() {
  $arr = array();
  forea         


        

Answer 1

From the PHP documentation,

$foo = new Foo();

$reflect = new ReflectionClass($foo);
$props   = $reflect->getProperties(ReflectionProperty::IS_PUBLIC);

foreach ($props as $prop) {
    print $prop->getName() . "\n";
}

var_dump($props);

Answer 2

To get a list of all public attributes call get_object_vars().

(Hint: calling it by the object itself will return all attributes.)

Answer 3

Make sure to follow some naming convention with your private variables (like i prepend them with _)

Then just return those variables that do not have _ in the beginning of their key.
